Modeling Contact and Resolving Convergence Issues with Abaqus
This course provides an in-depth discussion on solving nonlinear problems in SIMULIA Abaqus Standard with an emphasis on modeling and convergence-related issues for contact. Engineers at Abaqus have developed many techniques and guidelines for solving challenging contact problems. Convergence issues related to complicated material models and geometrically unstable behavior are also covered. Many years of practical experience in understanding and resolving convergence issues have been condensed into this course.
