Hi people,

I am using solidEquilibriumDisplacementFoam to generate a solution of a static linear simulation of a vehicle cabin with a pressure imposed but the code have diverged with few iterations. Does anybody knows this error?
The mesh was generated with netgen with +-50000 elements and the error seems not be influenced by DeltaT.

Thanks.

Hi,

Without knowing more about your case,

your case probably diverges because of either bad boundary conditions or a bad mesh or both.

You need to post more information about your case for more help, such as what boundary conditions you are using, and also whether "checkMesh" says your mesh is OK.

Also you should probably post this thread in the main openfoam forum, and not in the bug section.

Philip
