AUTODYN is a uniquely versatile explicit analysis tool for modeling the non-linear dynamics of solids, fluids, gas and their interaction. Our focus is on providing the most advanced capability and yet a very robust tool, backed up by first class support.
With a fully integrated, easy to use graphical user interface in the ANSYS Workbench Platform, AUTODYN offers:
- Finite element solvers for computational structural dynamics (FE)
- Finite volume solvers for fast transient Computational Fluid Dynamics (CFD)
- Mesh free particle solvers for high velocities, large deformation and fragmentation (SPH)
- Multi-solver coupling for multi-physics solutions including coupling between FE, CFD and SPH
- A wide suite of material models incorporating constitutive response and coupled thermodynamics
- Serial and parallel computation on shared and distributed memory systems
- Access to powerful geometry and meshing tools standard available through the ANSYS Workbench Platform
- Bi-directional connectivity to parametric ANSYS DesignModeler and CAD models
