Hi, I'm need to run Fluent in background using Linux cluster at four nodes.

I'm writting in shell:

fluent 3d â€"t4 â€"g â€"cnf=/home&hellip;/fluent.hosts < roda > output2>> errolog &

Fluent is started, but the nodes computes are refused. Could someone please suggest any alternate method to solve this problem?

Thanks in advance.

I am not sure if Fluent sets the communicator by default. But from your shell command, you seem to be missing the -px option.

This is the script that I generally use (part of a PBS script).

fluent 2ddp -t$ncpus -pnmpi -cnf=pnodes -g <run.inp> run.out

Hope this helps.

"fluent 2ddp -t$ncpus -pnmpi -cnf=pnodes -g <run.inp>out"

Thank for help.
