[Gmsh] help with hexahedra

[Pierre MOUSSOU]

Hello


I am currently trying to build an hexahedral mesh for CFD purposes, and I 
wished to use the "Transfinite Volume" command applied to quadrangular 
surfaces. I did not want to use the "Extrude" command because the 
numbering of the lateral surfaces is hard to predict. 

I succeeded in meshing surfaces with more than four sides, by defining 
four corners, as shown in the joint file. 

I expected to do the same thing with volumes, by defining eight corners. 
It does not seem to work, and the message indicates that only volumes with 
5 or 6 faces can be meshed with hexahedra. 

Is there a way to mesh my volume with hexahedra ? 

Otherwise, if only 6 faces volumes can be meshed with hexahedras, I do not 
see the point in defining six corners.


Thank you for your help.


With best regards
