The problem appear when you tr
The problem appear when you try to use engineFoam with mpirun. I've tried the parallel configuration with other tutorial cases (cavity, dieselFoam) and the problem does not appear.
According to the error below, it is a communication problem perhaps when the program try to calculate min(b) on all the cluster node. I also tried to different setup. On a cluster and on my personal computer (bi-proc) and the problem remained the same. So I don't think it is arch dependent. If you have any question to solve this bug, please feel free to ask.

Thanks. I fixed it in the 1.5.
Thanks. I fixed it in the 1.5.x git repository.
