Engineering Advantage BlogTap into the thinking of some of the world’s leading simulation experts.Our consulting engineers share helpful tips and insights into how they’ve solved significant engineering challenges.
You have a stubborn nonlinear statics model that won’t converge despite your best efforts. What do you do? You’ve tried adding substeps, modifying contact settings, and even changing solvers with no luck. An explicit solver might be the answer...
Many times, finite element simulations require us to consider problems that exhibit some form of nonlinear behavior. Whether it is large scale deformation, plasticity, or contact between bodies,...
Stress analysis engineers can now model complex nonlinear dynamic finite element analyses of very complex structures using distributed processing on a desktop computer. However, it is very difficult to isolate...
When performing complex finite element analyses, engineers typically bypass making the simplest, yet often most valuable, analytical model that can be...
