How to debug an External MaterialSolution Number: 1281 Applies to: COMSOL Multiphysics, Structural Mechanics Module Versions: All versions
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.Solution Number: 1171 Applies to: Structural Mechanics Module Versions: All versions
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 ...
Structural Contact Modeling GuidelinesSolution Number: 1102 Applies to: MEMS Module, Structural Mechanics Module Versions: All versions
This article contains guidance for solving models that include structural contact, and the procedures that should be followed to achieve a converged solution. Background Structural contact modeling is a highly non ...
