ANSYS Class 3 Error Reports
ANSYS Workbench 2015
Nonlinear material properties assigned to beam connections in Mechanical are not sent to the solver and therefore ignored during the solution process.
Surface-to-surface radiation loads (radiation scoped to faces), defined in Mechanical, can give erroneous results under the certain scenarios.
A rare but critical issue for users of remote design point update in Workbench has been identified. Under some circumstances, unexpected failure of a design point job can result in deletion of files on the client system at the end of the job.
The Details View of a user-defined result contains an Expression Detail that allows the user to enter either: 1. a simple result name (such as SX if he/she wishes to study normal stress in the x-direction), or 2. an algebraic expression that defines the result (such as one containing Identifier(s) from different results in the Solution). If the algebraic expression of a user-defined result "B" is a function of another result "A" and, if the By Detail of the user-defined result "B" is one of the following (listed in this report), then the values (e.g., contours legend, MIN, MAX) of the result "A" may be listed and displayed incorrectly. - Maximum Over Time or Maximum Over
ANSYS Workbench 2014
For shell elements that contain precisely one layer, the result displays for element nodal data like stress and strain are incorrect if the user selects both of these in the Details View.
Pressure loading on a MultiZone Quad/Tri mesh can have gaps in the applied pressure if the mesh gets a boundary input mesh and the size function is on.
Pipe Temperature loading is applied incorrectly in Mechanical for 3D structural analyses. Internal loading is applied to the outer surfaces of pipe elements and External loading is applied to the inner surfaces of pipe elements.
A design point update via RSM can result in incorrect design point data and parameter values, if (a) the project contains geometry that is either not parameterized or has identical parameter values between design points, and (b) the project contains engineering data that is parameterised.
For contact elements with STATUS=FAR (or equivalently STATUS=0), Contact Tool Results and Contact User Defined Results may report incorrect results. To conserve disk space, the solver, by design, writes no contact result data to the result file for these elements.
After creating a model with parameters in SpaceClaim, or importing a SpaceClaim model with parameters into WorkBench, the parameter values between WorkBench and SpaceClaim may not be correctly reflected. Parameters pushed from the WorkBench Parameter Set to ANSYS SpaceClaim Direct Modeler are not correctly reflected due to an issue in SpaceClaim and how their algorithm handles the convergence of parameters.
The Setup component of a CFX or Fluid Flow (CFX) system does not detect certain failures to refresh a mesh. In a number of situations (listed in document), the application will fail to load the updated mesh, and roll back to the previously loaded mesh.
For shell elements that contain precisely one layer, the result displays for element nodal data like stress and strain are incorrect if the user selects both of these in the Details View.
In a System Coupling analysis, the results after the 2nd step (or after a restart) will be incorrect if all of the following are true: 1. heat flow is transferred from the Mechanical System to FLUENT, and 2. there are multiple steps (or a restart), and 3. the coupled-field elements SOLID226 or SOLID227 are used
User-defined offsets for pipe sections are incorrectly defined in the solver input file. The SECOFFSET command is written in a wrong format resulting in the offsets being interpreted incorrectly.
If a Mechanical model contains shell or plane stress bodies and if a force reaction probe is scoped to a construction surface, then: 1. the legend in the graphics display window can contain incorrect minimum and maximum values for the nodal vector field, and 2. the contour coloration of the vector field can be incorrect. For this probe, the intended design of the display window is to place a reaction force vector at each node in the scoping. The color of the vector is a function of its magnitude. However, when the node lies on shell bodies or plane stress bodies, the reaction force contributions from the shell or plane stress elements are incorrectly added twice to the resultant vector. This leads to incorrect MIN/MAX values in the legend and incorrect contour coloration of the vectors in the display window.
While importing the solution into ACP the element shear forces and Von Mises stresses are not converted from the solution unit system to the ACP unit system. This causes all dependent post-processing results to be wrong.
When the missing mass effect is applied in a response spectrum analysis, the value of Zero Period Acceleration (ZPA) does not respect a subsequent change in the units when it is solved. The value of ZPA used in solution is always in the units in which it was defined.
When generating a low order mesh, exterior linear triangles along geometric edges may be associated to the wrong geometric face if all three nodes of the triangle are associated to more than one geometric face. They will be associated to the neighboring geometric face. This situation is more likely if the mesh is coarse compared to the size of the face, or if there is mesh-based defeaturing. Thus if a boundary condition (such as a load or contact region) is applied to the face, it will not be properly transferred to the solver and applied to an incorrect element face.
In ACP Post, a contour plot of reserve factors visualizes the minimum reserve factor per element. This requires a data reduction over all integration points per layer. This data reduction is wrong for SHELL181 with full integration because the reserve factor of the first integration point is shown instead of the overall minimum. The error becomes relevant in the case of high stress gradients within one element.
When performing calculations involving temperature quantities, quantity operators typically convert temperature quantities to an absolute temperature scale before performing the calculation. This is important because most physics laws are based on absolute temperatures. However, operations between a number and a quantity did not do this conversion to meet user expectation.
Modifications made to a duplicated ACP(Pre) system (for composite modeling) are ignored in subsequent Mechanical Analyses. Instead, the original ACP model is erroneously transferred to subsequently linked Mechanical Systems.
The volume computation for wedge elements through the Application Customisation Toolkit (ACT) API is incorrect. In some cases the computed volume is negative and obviously incorrect.
ANSYS Workbench 2013
In ANSYS Mechanical, the information given in the redundancy analysis table is not updated when the redundancy analysis is performed.
In the Mechanical application the results will be incorrect when certain conditions are met.
If a Mechanical analysis is restarted after a fully completed solution, and if the restarted analysis then terminates early before obsolete result sets are removed from the result file, Mechanical will incorrectly report the failed restart solution as fully solved rather than failed.
The term "mesh match" refers to the Match Control which is used to match the mesh of two faces or two edges in a model. "Mesh match" is implemented with "Match Controls" and anything under the Symmetry Folder. When performing a mesh in Symmetry region, Cyclic Region or in a Symmetry Folder, where inflation has been assigned or the MultiZone method is used, some nodes may fail to report match attributes to the solver. Match controls are not enforced when previewing inflation. Mesh generation may appear to succeed for a model featuring "mesh match" combined with Inflation or MultiZone methods, however, not all required node pairs are accounted. Thus, representation of the symmetry during solution or post-processing will be incomplete.
If the user has a Project Unit System that is based in a relative temperature scale (e.g.; Metric, where temperature is in C), Workbench Parameter expressions that include temperature may have the numeric portion calculated in an absolute scale (i.e.; Kelvin or Rankine), but units returned in the relative scale.
When using System Coupling, Workbench Mechanical serves incorrect data (temperatures or displacements) when multiple target regions in FLUENT correspond to one source region in Mechanical.
If the Workbench mesh contains pyramid-shaped elements and the user creates a path or surface result and the path or surface intersects such an element, then the results can be incorrect in the vicinity of the pyramid-shaped element. Additionally, if the user creates a result probe whose Location Method is either (1) Geometry Selection with an (x,y,z) pick or (2) Coordinate System, then the results can be incorrect if the (x,y,z) location is inside a pyramid-shaped element.
Force and moment reactions at remote displacements in a response spectrum analysis are incorrect when missing mass effects and/or rigid response effects are included in the acceleration excitations.
Due to multizone meshing in the Meshing Application not respecting symmetry controls, models with Cyclic Regions on MultiZone bodies may produce incorrect results.
The centroid of a multi-body part is not calculated correctly if the part contains a transformation from the CAD system.
Material data is transferred to Mechanical but is not assigned to any bodies. Mechanical is closed causing the material data to be saved with Mechanical. An edit to the unused material in Engineering Data will not be reflected in Mechanical unless changes, other than the material refresh, are also made.
Users should be aware that when a linear perturbation modal analysis is followed by a modal restart procedure, the stresses calculated during the modal analysis restart expansion are based on linear material properties.
If the '2D Behavior' property on the Geometry object is set to 'By Body', any imported thickness data applied in a 2D analysis will not be written to the input file and will therefore be ignored during the solution process.
In Workbench Mechanical, if the Display Option for a Maximum Shear Stress result is set to Elemental Difference or Elemental Mean, then the displayed contour values are twice the correct values.
If a MultiZone meshing method fails to mesh correctly, the solve button will not be disabled allowing the user to solve using an incomplete mesh leading to incorrect results.
In Mechanical, if the solver unit system is different from the intended unit system for the Temperature Scaling Parameter data the results will be incorrect.
When a high-order degenerated wedge or pyramid element is used in System Coupling, the received force is not correctly distributed.
After a prestressed Mode Superposition (MSUP) analysis is completely solved, any change made to the Constant Damping Coefficient of Engineering Data is not taken into effect for a new solution.
If the user creates a user defined result that is scoped to a surface or to a path, and if the user includes the identifier from a regular result in the expression detail, then the results might be displayed in the wrong.
In some situations, results given by joint probes for universal joints are incorrect and in other cases, joint accelerations are wrong.
Errors in the results from the solve can occure when the Material Model Damage Limitation Criteria is used and does not update after modifications.
Results in incorrect material model calculations from solver conversion of tempreture units.
The documentation for Solution Combinations in ANSYS Workbench Mechanical is obsolete and misleading.
In certain environments Contact Tool results may be displayed in an incorrect unit system.
Within the Mechanical Application User's Guide, the section titled Averaged vs. Unaveraged Contour Results is incorrect for solids and shells.
ANSYS Workbench 2012
The layer thickness defined in a Layered Section object and the membrane offset defined in a Layered Section, Thickness, or Imported Thickness object will be interpreted incorrectly if the active units do not match the solver units.
If the optional property Transverse Shear is added to the Gasket Model the units cannot be specified and the results will be incorrect.
Bolt Pretension Probes will be incorrect when a specific solution sequence is used. The results will be wrong when multiple environments exist and while one environment is in the process of solving.
If Imported Body Force density load is applied to a structural analysis using thermal conditions then the results will be incorrect.
Force and moment reaction probes in random vibration and response spectrum analyses will be incorrect if coordinate systems are not aligned.
In R13 and R14, a Workbench preference exists for the Mechanical and Meshing editors, this is turned off by default and may produce incorrect results.
For solution combinations and design assessments, Workbench does not correctly transform component strain results to local coordinate systems.
For element nodal results in solution combination and design assessment, the user's choice of the certain settings may be ignored.
Running a mode superposition harmonic analysis on a large model can result in the harmonic analysis solve being prematurely terminated.
A Coordinate System that was first defined by a "Geometry Selection" with a valid geometry, then modified to be defined by "Global Coordinates", will unexpectedly change location after a geometry update.
A Standard Earth Gravity load will not be written to the input file, and consequently will be ignored during the solution process, when certain conditions exist.
When using a parameter with unit Temperature Difference and performing a unit conversion, the wrong conversion is applied in some parts of the Workbench UI. This results in an incorrect value for the parameter.
Heat Flow loads that are defined in Thermal Electric analyses are incorrectly omitted.
The meshes generated in WB Meshing using the Assembly Meshing approach which are exported as FLUENT mesh file can have polyhedral cells which are bounded by faces which do not reference interior bridge nodes on edges.
Under certain circumstances, beams may not be assigned a sufficiently high stiffness and the resulting flexibility can alter the expected application of the remote boundary condition.
If a harmonic analysis produces imaginary result data, then a result defined by "Maximum Over Frequency" or "Frequency of Maximum" will be incorrect.
In a rigid body dynamics analysis, energy probes scoped on a body give incorrect results when model has contacts.
When the geometry and mesh data is refreshed into Mechanical after being created in FEModler, Mechanical will attempt to maintain associativity for any existing boundary conditions. However, this persistence can be wrong.
This QA Notice describes defects in nCode DesignLife reported in the noted nCode Customer Critical Communications that may affect ANSYS nCode DesignLife users.
User might report that they were recently working in Mechanical, and had either stopped a Mechanical solution, or a Mechanical solution had abruptly failed.
Under some circumstances, the database for a Mechanical or Mesh system can become permanently damaged upon saving a Workbench Project file.


ANSYS Classic 2015
When performing a mistuned cyclic mode-superposition harmonic response, and restarting the analysis with new mistuning parameters, all restart solutions disregard the new mistuning parameters.
All circuit components (KEYOPT(1)=0,1,2,3,4) of element type CIRCU94 and the inductor (KEYOPT(1)=1), capacitor (KEYOPT(1)=2), independent current source (KEYOPT(1)=3) and mutual inductor (KEYOPT(1)=8) components of element type CIRCU124 can produce incorrect results in a linear transient analysis if only the degree-of-freedom solution is written to the database (OUTRES,NSOL).
The results are incorrect when the coefficient of thermal expansion is defined using TB,CTE and is used in combination with certain material models as described in this report.
Linear analyses involving MPC184 elements that use the direct elimination method (KEYOPT(2) = 0) generate internal constraint equations. These internally generated constraint equations fail to trigger the program to reform the stiffness matrix at each load step. Without reforming the stiffness matrix, the solution may be incorrect.
Material table properties (input via TB command) that are functions of user-field variables and also a function of temperature or frequency are incorrectly interpolated during solution.
ANSYS Classic 2014
The derived stresses (S1,S2,S3,SINT,SEQV) for element type ELBOW290 retrieved using the *GET,,SECR command are incorrect.
Plastic strain energy density is incorrect if yielding occurs in the first substep for certain material combinations.
For an Explicit analysis, values returned for a probe scoped to a rigid body are incorrect. The minimum and maximum values are incorrectly obtained by querying the nodes of a single element on the body, rather than all elements on the body.
Harmonic analyses with viscoelastic materials (TB,PRONY) produce incorrect results for the following cases: A) PLANE182 and SOLID185 with enhanced strain and simplified enhanced strain formulations (for PLANE182: KEYOPT(1) = 2 or 3, for SOLID185: KEYOPT(2) = 2 or 3) B) SHELL208 and SHELL209 with significant bending deformations.
In acoustic harmonic response analyses (ANTYPE,HARMIC with FLUID30, 130, 220, or 221), the radiated acoustic power that is calculated with the POST1 far-field commands PLFAR or PRFAR is doubled when an infinite baffle exists and the sound hard boundary condition (HFSYM command) is used to replace the baffle for far-field calculations.
For ELBOW290 (the 3-D 3-Node Elbow), the axial, hoop, radial, and in-plane shear components are properly used to compute the section shear forces, but both transverse shear stress components through the pipe wall are incorrectly omitted. This is only significant for thick-walled pipes.
For eigenvalue buckling analyses (ANTYPE,BUCKLE), the torsional stress stiffness effects are not properly computed for BEAM188, BEAM189, PIPE288, and PIPE289, which may lead to incorrect results in a torque-dominant analysis.
When a non-zero degree-of-freedom constraint (D command) is specified at a node in a modal analysis that precedes a spectrum analysis (ANTYPE,SPECTRUM with SPOPT,SPRS or MPRS) with missing mass requested (MMASS command), the missing mass response is incorrect. All calculated quantities are incorrect including displacements, element nodal forces, stresses, and reaction forces.
For a linear analysis, results can be incorrect for material models with thermal expansion combined with anisotropic elasticity defined by TB,ANEL and TB,ELASTIC. Simulations that use a Newton-Raphson solution method with this material model are not affected by this error. The solution method is specified by the user or selected automatically and the user should refer to the NROPT command documentation and solution output to determine if a Newton-Raphson solution method is used.
If the STLOC field is left blank on a TBDATA command used to define data for the TB,SDAMP table, the value of STLOC does not properly default to 1. Hence, the data for the structural damping coefficient is not stored in the table and subsequently not used in analysis.
If a temperature in the model exceeds the maximum temperature in the temperature-dependent material data tables ANEL, BISO, and CONCR (TB command), values of zero for the material constants are used. This occurs when the number of temperature points is less than 6 and the maximum temperature in the table (TBTEMP) is negative.
Transient or harmonic solutions using the mode-superposition method (ANTYPE,TRANS with TRNOPT,MSUP or ANTYPE,HARM with HROPT,MSUP) may be incorrect if any one of certain is true.
When wear is simulated by using the TB,WEAR commands with contact elements CONTA174 over higher order tetrahedron elements (for example, SOLID187) or higher order degenerate brick elements (for example, SOLID186), wear is not calculated correctly for one of the nodes of the contact elements CONTA174. This leads to wrong overall results.
When no orientation node is used for the ELBOW290 element, the section offset (input on the SECOFFSET command) is processed in the wrong direction.
The documentation for performing a stress intensity factor (SIF) calculation is incomplete. The section affected appears in the Structural Analysis Guide: "Calculating Stress-Intensity Factors via Interaction Integrals." The documentation does not indicate that for 2-D axisymmetric stress states, the plane strain auxiliary field is used in the interaction integral formulation, possibly resulting in path-dependent values or incorrect SIF values.
In /POST26, the structural force and moment components at a node obtained using the ESOL command (Item = F or M) are incorrect for certain element types.
In a mode-superposition analysis (ANTYPE,TRANS with TRNOPT,MSUP or ANTYPE,HARM with HROPT,MSUP) with enforced motion (DVAL command), the results are incorrect in certain cases.
The displacements of contact nodes may be updated incorrectly when certain conditions are all applied.
The displacements of contact nodes may be updated incorrectly when certain conditions are all applied.
The slip rate used in a transient analysis (ANTYPE,TRANS) is mistakenly scaled by an internal factor depending on the transient integration parameters defined by TINTP. The solution will be incorrect when the slip rate effect is included using certain methods.
In a Multi-Point Response Spectrum analysis (ANTYPE,SPECTRUM with SPOPT,MPRS), the solution obtained with the Absolute Sum combination method (SPOPT,SRSS with AbsSumKey =YES) is incorrect.
In a structural-thermoelectric analysis (KEYOPT(1)=111) with PLANE223, SOLID226 or SOLID227 elements, setting KEYOPT(9)=1 to turn off the thermoelastic damping also turns off the Joule heating effect. Although the Joule heat is calculated, it is not applied as a thermal load.
ANSYS Classic 2013
In a mode-superposition analysis, the strains and stresses calculated for pipe elements are not valid when both: - internal or external pressure load is applied on these elements
During a large deflection (NLGEOM,ON) run, the original mass is not preserved for: 1. PIPE288 and PIPE289: All usages 2. BEAM188 and BEAM189: Only usages that include SECT,,BEAM,MESH with more than one material in the cross-section
In harmonic analyses (ANTYPE,HARMIC), the storage and loss material matrices for viscoelastic materials (TB,PRONY) are incorrect when using experimental data for the complex elastic constants input with the TB,EXPE tables. This causes the results of these analyses to be incorrect.
When using temperature-dependent density, the mass matrix is incorrect for certain cases. The mass matrix is used for all dynamic analyses as well as with any acceleration loads.

Errors in the material stiffness calculation will cause the results of the harmonic analysis to be wrong when table data is left undefined.
When using pipe elements PIPE288 and PIPE289 with cubic shape functions and three integration points along the length and using pressure and/or temperature loads that vary along the length, the loads at the second and third integration points are reversed.
