[Gmsh] Meshing of compound volumes

Hi Serban,

I don't know what the error message means.
What I know is that "Cut and merge faces" works only for planar surfaces, not for curved ones.
I am working on a solution for curved surfaces, but it is not finished yet.

Matthias

Dear Matthias,

Thank you for your quick reply.
Meshing worked fine after selecting the option you specified. However, when I tried the same thing with a more complex problem (e.g., lots of curved surfaces), I got the following error while opening the STEP file:

Error: TopOpenBRepBuild Builder::splitON

then I got again intersecting surfaces errors while meshing. Could the curved boundaries be the cause?

Thanks,
Serban

Hi,

you can try Options->Geometry->General->"Cut and merge faces" before meshing. This should work for duplicated planar faces.
A more general solution is being worked on (by me, actually...).

HTH,

Matthias

Betreff: [Gmsh] Meshing of compound volumes
Hi all,

I have  quick question regarding the meshing of compound volumes.
I have a simple geometry, basically two cubes stacked together and sharing one face. If I fuse the blocks, then there is only one volume and meshing works correctly. However, if I export as a compound volume, so two volumes sharing one face, Gmsh gives loads of errors. Is there a way to mesh such compounds in Gmsh?

Thanks for your time,
Serban
