elmwght for multiphsics


I am using Parmetis to partition multi-physics mesh (involving two meshes now). I am using V3_PartMeshKway function in Parmetis.
I am filling "elmwght" argument with 1 if it is the first mesh and 2 for the second mesh.
I am expecting each partition is load balanced for each mesh. However, I am only getting partitioning result as
same as if I fill "elmwght" array with single number (elmgwght has no effect).

What could it be wrong?

If you help, I will be glad.
