<html><head><style type="text/css"><!-- DIV {margin:0px;} --></style></head><body><div style="font-family:times new roman,new york,times,serif;font-size:12pt"><div>Hello,<br>I am wondering whether it is possible to define physical groups in a CAD geometry (especially using OpenCascade) which will be recognized by Gmsh in the meshing process.<br><br>I have created a simple geometry using Salome, named the primitive bodies and their boundary faces, and imported it as BRep file into gmsh. However, the resulting mesh contains no physicals.<br><br>Is it possible to define physical groups using CAD tools in the BRep file, or do I have to define them manually in Gmsh? What are the required steps?<br><br>Thanks<br>Jan<br></div>
