Hello,

I'm quite new to OpenFoam and I'm trying to learn how to simulate rotating movement. I'm getting the following error when trying to run a parallel case for rotating fan in room tutorial:

--> FOAM FATAL ERROR:
[1] UPstream::init(int& argc, char**& argv) : environment variable MPI_BUFFER_SIZE not defined
[1]
[1] From function static bool Foam::UPstream::init(int&, char**&)

Hope somebody is able to help as I've looked for answers online but now I'm quite stuck.

Full script after running mpirun command:

rbytautas@Tomas-PC:~/OpenFOAM/OpenFOAM-v2006/tutorials/incompressible/pimpleFoam/RAS/rotatingFanInRoom1/case$ mpirun -np 4 pimpleFoam -parallel > log.pimpleFoam &
