SIMULATION DEBUGGING SERIES
Step-by-step guide to fixing convergence errors in SimScale non-linear FEA. Learn to manage contact stiffness, Newton-Raphson iterations, and hyperelastic material stability.
There is nothing more frustrating in Computer-Aided Engineering (CAE) than a simulation that crashes at 99%. In non-linear Finite Element Analysis (FEA)—whether you are dealing with large deformations, plasticity, or complex contact—convergence failure is a rite of passage. This guide skips the basics and dives into the solver-level adjustments needed to stabilize your SimScale runs.
