CBC.PDESys

Problem running Demo

Asked by Alexandra Diem

I have just installed Fenics and CBC.PDESys and wanted to run the demo scripts Lshape and turbulent_channel. When I try to do so I somehow get MPI errors:

Fatal error in PMPI_Comm_size: Invalid communicator, error stack:
PMPI_Comm_size(111): MPI_Comm_size(comm=0x99ef2a40, size=0x7fffafe869cc) failed
PMPI_Comm_size(69).: Invalid communicator

Where does that come from?
Thanks!

Uninstalling MPI and reinstalling Fenics has solved my problem. There seemed to have been a clash between different versions of MPI.
