I'm trying to conduct finite element analysis on imported .stl models from SketchUp. I can't seem to generate an ElementMesh. I think it may be something to do with intersecting boundaries, and this question asked here (3D internal subregion\ subregion) is perhaps relevant. Does anyone have any good methods of importing models into Mathematica, and then turning them into meshes?
<< NDSolve`FEM` model = Import[plank1.stl"]; (*plank1.stl in linked dropbox file*) repairModel = RepairMesh[model]; bmesh = ToBoundaryMesh[repairModel]; mesh = ToElementMesh[bmesh]
