Quadrilateral 3D mesh generator

[Gary L. Roach]

Hi all,

I can find plenty of open source triangular mesh generators (gmsh,
netgen, etc) but can't seem to find one that produces a quad mesh on
complex 2D and 3D shapes. I run a Debian system and usually try to stick
to .deb packages. I this case there doesn't seem to be any. In a pinch,
I can compile from source code. Any suggestions?

Gary,
gmsh can generate quadrilateral meshes. I don't know what its status is with
regard to hexahedra in 3d, but it's a high quality code that I'd give a try.

Best

Hello Gary,

Gmsh has an option to create quad mesh. After creating the surface, add ‘Recombine Surface{surfaceID}’ (in .geo file) to generate the quad mesh on ‘surfaceID’,

Hope this helps,

Rakesh

Hi Rakesh

After much fooling around, I finally settled on Salome. The documentation is pretty good and it does a beautiful job of creating a Hex grid. I found gmsh too limited and clumsy. OpenFoam was impossible to understand due to the terrible documentation. Salome took in a FreeCAD 3D .step object and produced a quite good .unv starting grid.

Thanks for you help.
