This is a simple test (follow up to http://elmerfem.org/forum/viewtopic.php?t=7840) of a magnet moving next to a metal piece. For a coarse mesh I get reasonable results, for larger models I am trying to use mpi to solve the case. However, to make the case work I need to have both mortar surfaces on the same partition leading to an unbalanced load. For instance, if I use the following command:
Code: Select all
ElmerGrid 2 2 simple_test_symmetric -partdual -metiskway 4 -connect 3 9
Code: Select all
Saving mesh for 4 partitions
part elements nodes shared bc elems
1 14648 3720 1338 3846
2 9205 2328 595 1739
3 9465 2451 426 965
4 9154 2590 627 888
Questions: Is there any strategy I can use to get better balanced partitions? Is there no other alternative than having all mortar elements in the same partition?
Cheers,
Francisco
