Problem in parallel Fluent under Ubuntu (loading MPI?)
 
Hello,
I just installed a version of Ansys14.0 in Ubuntu.
In serial mode everything works fine but I cannot start properly the parallel (on a local machine) version.

This is the message I get (in the bottom lines part is where, I suppose, problems arise)
Can someone please help me?

Ok guess I solved it
if I run Fluent as:

fluent -r14.0.0 3ddp -t4 -mpi=openmpi

basically I choose manually the mpi library I want it works.
I don't know why it doesn't like the pc mpi one but beeing practical
I will going on using openmpi.
