Building Better Boundary Conditions e-Learning Presentation

This presentation accompanied the Building Better Boundary Conditions ANSYS e-Learning session, originally given in December 2012 by CAE Associates.  To view a recording of the session, click here.

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
