[Gmsh] Grouping vertically-alighed nodes in Extrude command

[Daniel Wheeler]

Hi,

I have been looking into a similar issue. I noticed in the manual that
there is binary option "Mesh.PartitionByExtrusion", which may achieve
what you want. However, it seems that this option is no longer
available on trunk (r12321).

My question to the list: Is there is any way to ensure that a
particular geometric entity (whether extruded or otherwise) solely
occupies a given partition of the mesh? Looking in DefaultOptions.h
and searching on "part", doesn't seem to throw up any obvious answers.

Cheers
