Building Better Boundary Conditions - ANSYS e-Learning

Posing the following question for 20 years to ANSYS students:  What is the most common and largest source of analysis error? has resulted in the same answer over 90% of the time.  It is the boundary conditions!  Bad boundary conditions are often the hardest to detect and cause the largest solution errors.  All models require boundary conditions.  It is also rare where the fixed, pinned, sliding supports, etc. are easily defined.  Proper boundary conditions can save modeling and solution time and result in more accurate analyses.


CAE Associates’ Vice President Peter Barrett guides you through a series of tips and tricks for creating effective and realistic boundary conditions through detailed examples.  You will learn how to:

  • Apply symmetry, anti-symmetry, and cyclic BC’s
  • Efficiently utilize remote points to apply displacements, or create masses
  • Apply Coupling and Constraint Equations
  • Apply nodal-based displacement
  • Harness the power of advanced connections

If you are unsure of the accuracy of your boundary conditions in Workbench Mechanical or want to improve your modeling techniques, you should view this e-Learning session.
