Hello all, I faced a problem with work with stl formats. I need to make volume mesh and import it in a FEM solver. I can do it by merge stl file and define a volume and then make 3D meshing. but after importing in FEM solver I don't have access to physical information of surfaces and volumes. I need to have my part not only as a physical object also as a set of physical faces (surfaces). I mean I need to chose specific surfaces (face of a volume element that belongs to surface of object) to apply boundary conditions, but my object has an overall surface. attachments are stl information and my effort to make a physical object with volume meshes. but still I don't have access to the surfaces that define the volume. How can I define physical surfaces on my object? It is very kind of you if help me with this problem.

femur.stl
Description: femur.stl
// merge a surface mesh (any format will work: .msh, .unv, etc.)
Merge "femur.stl";
// add a geometrical volume
Surface Loop(1) = {1};
Volume(1) = {1};
Physical Volume("volume") = {1};
// use this to force a coarse mesh inside
//Mesh.CharacteristicLengthExtendFromBoundary = 0;
//Mesh.CharacteristicLengthMax = 0.5;
