I had the very same problem. I also tried the text file. Did not help. I can spawn process on the second processor on the double processor machine, however I cannot do it on the other computers. So far I did not find a solution. No firewalls, two computers directly connected via appropriate cable and still nothing.

Have you tried the -pnet and the -pnmpi options?

fluent 3d -pnet -t(n) -cnf=(hostsfile)

or

fluent 3d -pnmpi -t(n) -cnf=(hostsfile)

I don't think the other comunicators allow you to spawn across mulitple machines. Also, you can use:

fluent 3d -pnet -t0

And then go to Parallel->Network->Configure and manually spawn compute nodes. I think the benefit to doing it this way is that if there is an error it shows up in the Fluent window, whereas the error doesn't always show up if trying to spawn from a hosts file.

Hope this helps, and good luck, Jason
