I'm trying to mesh a part that was imported from a Pro-E part as an STL file.

I can mesh small pieces of it if I make cuts, but that doesn't really help me. I have tried curvature meshing, meshing "As part"/ Tried courser and finer mesh, nothing work, it automatically throws an error. I'm trying to do a drop test.

I'm really new to Simulation and am feeling my way around without any training yet.

Any help would be greatly appreciated.
