Hi all,
I am using FoamExtend 3.1 for my simulations. It runs fine using the sparseimage on mac osx in serial but doesn't run in parallel.

Any leads on resolving this issue would be appreciated.
Thank You.

Hi,

Do I get you right: you're proposing someone to download sparseimage, mount it, and run parallel simulation from tutorial to see the error?

And it's not the fact that person will get the same error you're getting on your computer.

Hi Alexey,
In fact, what I intended to ask was, how do one run parallel simulations on OSX.
I have tried running the tutorial cases in serial and they run. But when I try running in parallel using mpirun, I get the following error:

"--> FOAM FATAL ERROR:
Trying to use the dummy Pstream lib

--> FOAM FATAL ERROR:
Trying to use the dummy Pstream library.
This dummy library cannot be used in parallel mode

From function Pstream::init(int& argc, char**& argv)
in file Pstream.C at line 39.

FOAM exiting"

Hi,

This message usually means that foam-extend was built without MPI support. What is the value of WM_MPLIB environment variable?

Hi,
I am sorry for getting back late on this.

This is what it reads.

                fi
            fi
        fi

The path for the current mpirun is "/opt/local/bin/mpirun".

I have one more question, is there a way I can install OF without having to use the sparseimage on the MAC OSX?
