<DIV></DIV>
<DIV
style="FONT-FAMILY: times new roman, new york, times, serif; FONT-SIZE: 12pt">
<DIV>Hello!</DIV>
<DIV> </DIV>
<DIV>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.</DIV>
<DIV> </DIV>
<DIV>Is there a better way to do this? Can I repair the missing surfaces?</DIV>
<DIV> </DIV>
<DIV>Thanks for any help you can provide.</DIV>
