[Gmsh] Mesh STEP file

[Zenker, Dr. Matthias]

Hi Marc,
 
when I mesh your geometry (without defining physical groups) and open it with Elmerfem (www.csc.fi/elmer), I can see all surfaces as boundaries. So they must be in the msh file. The problem may be the way your cfd software reads the msh file.
 
HTH,
 
Matthias

Betreff: [Gmsh] Mesh STEP file


Hello!
 
I am trying to mesh the attached STEP file in gmsh 2.4.2 and define boundaries for a cfd solver.  I can merge the file and select the relevant surfaces and volume as physical groups but after I mesh to geometry, I open the .msh file created and cannot see the boundaries I defined.  I tried saving the geometry as a .geo file but surfaces are missing at the pipe intersections.
 
Is there a better way to do this? Can I repair the missing surfaces?
 
Thanks for any help you can provide.
 
Marc
