Running OpenFOAM from Platform LSF

Does anyone have any experience running OF from LSF? If so, could you share an example shell script to submit the job to bsub?

Posting this in response to a PM from member Linse. Sorry if this info is posted elsewhere but maybe others will find it helpful.
The key is the LSF environment variable $LSB_HOSTS which is the lists of machines assigned for your job. Create two files e.g. "parjobscript" and the "runparjob"
for i in $LSB_HOSTS
do echo $i >> machineFile
mpirun -n 20 --hostfile machineFile simpleFoam -parallel > foam.log
bsub -q limit150 -n 20 -e error.%J.log -o output.%J.log < parjobscript
The -n option in each of these files should be followed by the number of processors you want. In "runparjob" I'm submitting to the LSF scheduler using bsub, followed by the queue name (in this case limit150) and again the number of processors. The -e and -o options specify the error and log files respectively (using %J gives you the current job number).
Executing "runparjob" should assign the assigned LSF machines to OpenFOAM.
Hope this helps.
