Mesh failed

Hi Experts

Does anyone help me to understand why these meshes are failing. I just opened the model in Nastran and generated the mesh. But this was the result, couldn't find out why this is happening.

Hi,

It's difficult to reply without seeing your model (at least images of failing parts). Maybe the parts with red crosses are too small for your mesh size (the mesh size is too large), or they contain some sliver faces, or just their geometry needs to be rebuilt. Hard to say...
