[Trilinos-Users] Exodus and MPI

[Shota Soga]

HI Andrea,

When you run Sundance with multi-dore, it asks to distributed mesh by
default for parallel computing.

I do not know how to generate distributed mesh with exodus (probably Cubit
can do this?), but in the source directory, I thought there is python
script to convert Exodus file to partitioned triangle mesh. Then, use
Triangle Mesh reader for partitioned triangle mesh.
