RE: Parallel job in Vista-32

I'm a relatively new user of FLUENT/CFD and am curious as to how to properly set up my single Q6600 machine to run parallel simulations. So far, I have yet to see any performance increases running through "Parallel FlUENT" and serial FlUENT. In addition, using the FLUENT launcher in parallel mode usurps 75% cpu without even having loaded any *.cas file.

Some questions: 1) Must I set up a host file? 2) In fluent launcher, since I'm using a 32-bit O/S, I only have access to the following MPI options (default, mpich2, net). Which should I be using? 3) Are parallel jobs dependent on having a proper license key?

Regards, Kevin

Re: RE: Parallel job in Vista-32
Very easiest way to do it.....without knowing any thing.....

just right click on fluent shortcut and somewhere it says application location like as follow....


just change it to

c:\Fluent.Inc\ntbin\fluent.exe -t4

that is it....enjoy....

-t4 means four processors.

-t2 means two processors....
