How to debug an External Material

Número da Solução: 1281 Aplica-se a: COMSOL Multiphysics, Structural Mechanics Module Versões: Todas as versões

I have a implemented an external material for use with Structural Mechanics, but my model is not solving. External materials are coded in C, and then compiled into a shared library that COMSOL Multiphysics uses at ...


Manual tuning of the Contact Pair condition.

Número da Solução: 1171 Aplica-se a: Structural Mechanics Module Versões: Todas as versões

In COMSOL 4.3b, the contact pair conditions were changed to improve manual tuning of the augmented Lagrangian contact formulation. In the augmented Lagrangian method, the penalty factor controls how “hard” the ...
