<div><br>
<div><span style="font-family:'Segoe UI',Helvetica,Arial,sans-serif">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. </span><br style="font-family:'Segoe UI',Helvetica,Arial,sans-serif">
<span style="font-family:'Segoe UI',Helvetica,Arial,sans-serif">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?</span><br style="font-family:'Segoe UI',Helvetica,Arial,sans-serif">
<span style="font-family:'Segoe UI',Helvetica,Arial,sans-serif">It is very kind of you if help me with this problem.</span></div>
