Dear all,

I am new here but I used OpenFoam a few years ago under Ubuntu.
I now try some new versions of OpenFoam and I come back to Ubuntu.

I work under Ubuntu 14.04.2 LTS.
I try to install OpenFoam 2.3.1 (for compatibilty reasons with previous works).

I followed the procedure described on this page :
http://www.openfoam.org/archive/2.3....oad/ubuntu.php
but I have some problems when I verify that everything is ok.
Paraview is launched perfectly but I can't lauch Openfoam. When I type

icoFoam -help

I obtain the following error :

icoFoam: error while loading shared libraries: libmpi.so.0: cannot open shared object file: No such file or directory

I've done a research on the web and on this forum but I've found nothing that can help me. As it's wrtitten, it seems that the file "libmpi.so.0" is not present on my system, which is true...
Actually, I think it's a problem of OpenMPI installation or configuration but I can't find a solution to install and configure them correctly.
OpenMPI is installed and is located here : /usr/lib/openmpi

Thank you very much for the help that you could give !
Best regards,
