Hi Xuemin, brief answer:
Close the ends of your tubing and define a volume using this closed surface. You can do that either in Solidworks or in gmsh. To do it in gmsh, you will need to write a geo file starting with a merge command for your iges file. See gmsh documentation for more info. Then you can do the 3D meshing with gmsh. For physical surfaces, you can add a command to your geo file, see gmsh documentation. HTH, Matthias Von: 王学敏 [mailto:[email protected]] Gesendet: Donnerstag, 13.

Attachments are IGS file and msh file. You can see I just get mesh on the surface and I do not know how to define physical surface. I want to get mesh inside and on the surface. Thank you so much. Best regards, Xuemin _____________________________________________________________________ ERBE Elektromedizin GmbH Firmensitz: 72072 Tuebingen Geschaeftsfuehrer: Christian O.
