I have a 3D design of a spiral like shape made in AutoCAD (format: .dwg, .dfx). I need to make a series of FEM calculations (for which I haven't yet determined the equations) on that model using Mathematica..
I understand how to apply the FEM methods/functions to a mesh and obtain the desired results. But how do I use the shape in the CAD file as a mesh? I've managed to import the file and visualize the shape, but can I turn it to a convenient mesh in Mathematica?
