Hello Dave,Thank you very much beforehand for your attention. I had a look about what you said regarding that surface between the 291 and 299 one, and it seems to be it is defined because when I click on "Elementary Entities", "Add", "New", "Ruled Surface", it shows me dotted lines on that surface and it says to me that surface is: Ruled Surface 295 {272,294,283,290}
OK, I didn't saw it because the surface 295 is not part of Physical Surface(4) You should make tests with a smaller cube and a coarser mesh, and also try the front3d meshing algorithm. The good news is that I was able to mesh the volume like this: gmsh Desktop/Walkie-Talkie.geo -clscale 2 -algo front3d -3 Regards, Dave
I would be really grateful if you could clarify this to me please as I did not get what you meant. Perhaps, I am missing somethin out and I am not realising.
