OK, it appears that I solved last-weeks issue with the files, turns
out one of the nodes did not have the correct paths (thanks).
However, now I am still having problems when using more than one node,
this time ASPECT just hangs on time step 1, no error, the
solution-00000 files are created on each of the nodes than nothing.
It runs fine on a single node. I should point out that the ASPECT
example stokes.prm as well as Citcoms runs on the cluster without
issues.
Here is the log.txt for the convection-box-3d.prm -- thanks in advance Rob
