What causes Inverted Mesh's
What causes Inverted Mesh's
(OP)
I am new to FEA. I am having some trouble with a simulation stopping due to an "inverted mesh."
What sort of geometry would cause this? What sort of changes should I preform to rerun the simulation?
Thanks.

Last, are you doing a fluid dynamics simulation or stress analysis? This is a fluid dynamics forum, not a FEA (which is more classically for stress analysis) forum...
RE: What causes Inverted Mesh's
Yes my simulation is actually a mechanical stress simulation.
My previous experience is only with CFD simulations. I was not familiar with a mechanical stress simulation folder/section. I was hoping the mesh generation was similar.
I specified 4 regions mesh size, and then used an automatic mesh (in the program - comsol).

It is a part file, and there are 4 holes in the part.
I "reworked" some of the geometry to get rid of fillets and other complicated features.
Thanks for your input!

Hm. I wouldn't think a high-end product like that would have auto-meshing issues. Have you talked to the vendor, and what did they say? Can you try meshing without specifying the mesh density at first, and let it get a coarse solution, then increase the mesh density after getting the initial coarse mesh.
