I sincerely apologise if this question is a duplicate. Though it is clearly a question that must have been asked and answered a 1000 times I can't find any reasonable solution.
How do I take a simple 2D CAD Drawing (.dwg file) of a 2D boundary and generate a 2D computational mesh suitable for FEM analysis in any of the following file formats:
.xml (DOLFIN XML), .ele/.node (Triangle file format), .mesh (Medit generated by TetGen), .msh/.gmsh (Gmsh), .grid (Diffpack tetrahedral), .inp (Abaqus tetrahedral), .e/.exo/.ncdf (Sandia Exodus II), .vrt/.cell (Star-CD)
I'm doing this on my own time so it must be free software. Any assistance would be greatly appreciated!
