Obtaining & Optimizing Structural Analysis Convergence

This presentation was given by Peter Barrett, M.S.C.E., P.E., Vice President of CAE Associates at the ANSYS Confidence by Design Workshop in Morristown, NJ in April 2012.  If you have any questions about this presentation, please contact us.

Most structural mechanics simulations are non-linear and thus convergence is not guaranteed. Nonlinearities can be a result of non-linear material models, contact, and large deformation. The goal of this presentation is provide details on how to diagnose non-converged solutions and to develop an efficient analysis process.

Topics discussed include:

  • Example Problems – Characterize Convergence Difficulty
  • Step-by-Step Convergence Tools
  • Demonstration
  • How to Leverage the Robustly Converging Model
