<br><font size="2" face="Arial">i have a question to your great tool gmsh:</font>
<br>
<br><font size="2" face="Arial">Is there any possibility to generate a three-dimensional
geometry (with several domains (=different materials) with an external
software</font>
<br><font size="2" face="Arial">then import and mesh it with gmsh?</font>
<br>
<br></blockquote><div><br></div><div>Yes : we handle STEP, BREP and IGES inputs.</div><br><blockquote type="cite"><font size="2" face="Arial">I have tried this with freeCAD and exported
a brep-file of my geometry but the problem is that common faces of volume
bodies in the geometry</font>
<br><font size="2" face="Arial">was saved twice (each belongs to one domain)
and so the gmsh' mesh-algorithmus was not able to mesh the domains correctly.</font>
<br>
<br></blockquote><div><br></div><div>It is possible that freecad outputs volumes that have one face in common and that face is duplicated. In this case, our basic 3D mesh</div><div>actually fails because all volumes are meshed together and this particular situation generates duplicated points. We can imagine to</div><div>modify the algorithm and mesh series of connected volumes together. Another way is to save volumes separately with freecad, mesh</div><div>them and merge meshes.</div><br><blockquote type="cite"><font size="2" face="Arial">Maybe there is another way, generating a
3D-geometry (should be scriptable) and match the domains with material
properties so that getdp could solve the problem.</font>
<br>
<br><font size="2" face="Arial">Do you have any ideas or hints?</font>
<br>
<br><font size="2" face="Arial">Thanks in advance for your help</font>
