<div dir="ltr">Hi,<div><br></div><div>I have a 3D mesh and want to assign part of the surface to a physical surface with a specific label. But it seems that I have to modify the whole geometry to include this surface and it looks like I have to redo the whole geometry again. Is it possible to assign a part of a surface as a physical mesh without having to create this subsurface explicitly and re-meshing everything around it?</div>
