<p class="MsoNormal"><span lang="EN-US" style="font-size:12.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:12.0pt">I am currently working on a system which is aimed at automatically generating meshes for specific CAD models. The CAD model has different boundary conditions on different surfaces, so I have to
create several physical groups for the model.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:12.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:12.0pt">The problem is, I cannot find a proper way to pass the boundary conditional information to gmsh. All the geometries in gmsh are identified by numbers, which would change when the CAD model is
topologically changed.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:12.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:12.0pt">I had once developed a similar system. In that system, I paint several colors on different patches of the CAD model and then read the color property of the exported *.step file. In gmsh, however,
I didn’t found proper geo command to read CAD properties (such as model color) from step files.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:12.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:12.0pt">So, anyone please tell me any proper route to port the boundary condition information from CAD to gmsh? Thanks a lot!<o:p></o:p></span></p>
