Elmergrid mesh partitioning

Post by mark smith »

Hi All,
I have a mesh of which I wish to partition using elmergrid. As the mesh is composed of mixed element types tets and prisms "elmergrid 2 2 mesh -metis n" fails is there a reccomended alternative method? I've tried elmergrid 2 2 mesh -part 2 2 2 but this produces a mesh identical to the original?

Regards
Mark

Hi Mark

See page 61 in:
http://www.nic.funet.fi/pub/sci/physics ... Manual.pdf

The Metis routines marked with 2, 3 and 4 should work with hybrid meshes. You might also use
"-partdual" flag for prettier partitioning. So for example

Code: Select all

ElmerGrid 2 2 mesh -metis 64 3 -partdual

Hi Peter
Thanks very much, works like a charm ;-)
Is there likely to be much difference between the different options you suggested?

Best regards
Mark
