The most problematic scenario engineers encounter when analyzing large deformation solutions using the finite element method is convergence issues due to mesh distortion.
This is typical, for example, during simulation of elastomeric sealing or metal forming applications. Complex nonlinearities due to mechanical and/or thermal behavior arise in such cases from inherent material properties, geometric changes and establishment or separation of contact interfaces. The latest “NonLinear ADaptivity” (NLAD) feature and accompanying enhancements are as automatic as one can imagine for repairing mesh distortion, overcoming convergence difficulties, refining the mesh to capture local phenomenon and achieving the “true” design solution.
