Structural Simulation: Resolving Convergence Issues
Obtaining converged solutions for highly nonlinear simulations can sometimes be challenging. Difficulties can arise, especially in simulations involving contact, complicated material models and geometrically unstable behavior. This course provides an in-depth discussion on solving nonlinear problems and addressing the most common convergence-related issues. Many years of practical experience in understanding and resolving convergence issues have been condensed into this course.
