Advanced Contact & Fasteners

Who is the course for

This course is designed for people who wish to fully understand and analyse the contact non-linear phenomena in the ANSYS environment. Attendees should be familiar with iterative solution techniques in ANSYS and have performed simple contact analyses as encountered in the Basic Structural Non-linearities course.

Duration

2 days

Course Aims

  • Take full advantage of all the capabilities of the ANSYS contact elements.
  • Select the appropriate contact element, element options and characteristics for an efficient solution.
  • Diagnose and correct convergence problems.
  • Use contact elements in multiphysics applications.
  • Validate the results from a contract analysis.
