I was wondering if anybody here could suggest, if possible, how I may create a 3D geometry in Comsol from an imported STL file. The STL file is a scan of a femur, with two distinct regions: the inner bone marrow canal and the outer layer of cortical bone. I know that this would not be an issue with the CAD import module, but I am not bleeding money to be able to afford that.
Every time I have tried thus far, I receive warning messages about intersecting faces and trouble with edges. I have tried generating an extremely fine mesh in SOLIDWORKS only for Comsol to crash due to the file size. Even when reducing this super mesh to something more agreeable, Comsol still has issues with faces and edges.
Is there another piece of software out there that can render an STL file in such a way that Comsol would happily use it? OR is the STL file format just no good for setting up a FEM simulation?
Thank you,
David
