Issue with Comsol on clusters

Hi,

I'm trying to run COMSOL on our cluster and I run the command "comsol -nn 1". What I get is the following message


grep: /usr/local/comsol43/bin/glnxa64/comsolcluster.ini: No such file or directory
grep: /usr/local/comsol43/bin/glnxa64/comsolcluster.ini: No such file or directory
/usr/local/comsol43/bin/comsol: line 1146: /usr/local/comsol43/ext/impi/glnxa64/bin/mpiexec.hydra: No such file or directory

Do you know what to do to fix this issue?

Thanks,

J
