[Gmsh] Problem generating a hole inside a volume

Mon Feb 24 09:40:17 CET 2014

Hi,

I have had a look at your geometry and don't see any problem obvious to me (I am not familiar with the extrude, translate and duplicate commands, so I cannot tell if the problem is there). When I try to mesh, my gmsh crashes already while generating the 2D mesh (2.8.3, Windoze 7). So I'm afraid I cannot help you here.

Hello and thank you Dr Matthias for your help

I need to generate a volume that has inside other two perpendicular volumes, which also need to be meshed. I tried to do this defining each of the interior volume independently and the create the exterior volume with a hole inside.

I am not sure if this is the best way to do it, but I can't generate the 3D mesh, neither changing geometries nor changing 3D mesh algorithm. I avoid crossing surfaces but still can't get it.

I have attached the .geo file, which is a simplification of my model, with the surface loops and volumes.

If you can take a look at it and see if you can find where is the problem I would be very grateful, at this time I don't know what else to try.

Hi all,
I am kind new in mesh generation, is not my expertise area at all.
I am trying to generate a 3D mesh to a volume with a hole inside, seems to be very simple, but I tried everything (hope not everything) but couldn't got it. I tried changing my volume geometries several time, changing my 3D algorithm to frontal, etc etc but none of these worked.
I attached a .geo file (simplified model), which is a simplification of my model, with the surfaces loop generation and the volume.
If you can take a look at it and see where is my problem I would be very grateful, at this time I don't know what else to try. \
Thanks
Mauricio
