Metis partitioner failure or mesh issue?

[Rajeev Jain]

mbpart -m ML_RB 20 newcubex2b.exo 2b_20p.h5m fails with error: Partitioner failed! Error code: MB_MULTIPLE_ENTITIES_FOUND (5)

This comes when it is trying to assemble the graph: src/MetisPartitioner.cpp, line 404 to 431. It tries to loop over all the hex27 elements and fails with the above error.

The attached mesh can be successfully partitioned with zoltan.

It seems like a problem with surface boundary (sidesets) sets. The zoltan partitioned file fails to load in parallel. --

Can we mark this as resolved ?

[Rajeev Jain]

Yes, works now.

The problems was with the original .exo file.
