Hi All,

I'm using compressibleMultiphaseInterFoam for some work I'm doing, I have 2 computers, 1 is a fairly standard quad core, 8GB of RAM etc the other is a Twin CPU workstation. The case I'm running works fine on the normal machine but I get a segmentation fault on the workstation. Both have identical software stacks, Ubuntu 12.04, OpenFOAM 2.3.0 installed from repository.

Error is as follows:

Segmentation fault (core dumped)

I don't understand how it's happening on one computer and not the other when all software is meant to be the same.

Any help would be greatly appreciated.
