I'm trying to do a structural analasis on a 3 d printed cast from a company called ActivArmor. The cast shape is very organic looking and because of that the STL file I was given is made up of thousands of triangles. I have left the simulation running for days and it cannot compute the mesh in that amount of time. Has anyone else been able to run simulations on complicated models made of thousands of faces? What is the problem/solution? Do I need more RAM?
