Hello! I have following problem regarding Fluent on a cluster. The calculations run fine but when I want to save with the autosave command it takes up to 1 hour to save a 70MB large data file. I also get following message in the command window which I never had before:

"Host receiving summary from compute node zero. Writing "/array/clemens/estonia/empty/deck4_vinlet_poutlet-0001.dat"... Host receiving injections from compute nodes. freeing host particles. Done."

Does anybody know what could cause this slow down? Thanks for any help! C.

The messages you get on the console are normal, don't be worry about them. Which communicator do you use? try the -pnet option, is not the fastest one in communication, but for writing files in parallel is the best.

Thanks for your help!
