Hi all,
I'm new to comsol, and since I don't have access to a wind tunnel currently I'm trying to test lift and drag coefficients on some 3d models. The model is a 3d lizard made in blender and it is very complex. I usually export the model from blender as an stl, then use a separate program to convert it to a step file.
Unfortunately I'm having some trouble importing my model (which I designed in blender) as a solid. I can import it as a mesh stl, however when I try to import as a solid step file I get "internal error in geometry processing, internal error code 900".
I tried completely simplifying the model in blender, and when I do it imports as a solid, but it takes hours to load and comes up with dozens of errors.
What can I do to successfully load in this complex model? Should I give up on using blender (which I'm now acquainted with) in favor of a different program? Any ideas?
Thanks, Jaden
