I have a system with two dual-core AMD-64 bits processors. Running a single FLUENT-problem approx. 25% of maximum CPU performance is used and in 2-node parallel mode approx. 50% of max. is used. How can I use more of my CPU-speed?

Get several parallel solve licenses. FLUENT is licensed per processor or, in the case of dual-core machines, per core.

I tried to use parallel modes, for 2 processes indeed 2 cores are used. But 4 processes didn't use 4 cores. Maybe the communicator is the problem?

Hi!

I have 2 x AMD DualCore Opteron processors, and Fluent uses just 1 licence!! Is ther something wrong??

We do have 6 licences, how to say Fluent to use more than one??

You have to disable it as soon as possible!!!

hurry up!! haha, it was a joke. but, you have to do it.

go to the BIOS, then turn the dualcore mode off.

good luck

1 FLUENT license runs on 1 processor (core). If you want to use multiple processors (cores) you need to do a parallel run and specify the number of licenses to use (up to the limits of your software license, of course).
