Ansys 14 installation on Dual Processor machine

I need to know how can I install Ansys 14 on a dual processor machine to make use of all the available cores.

Just install the whole Ansys package. There is no separate procedure to make it compatible for parallel process.

I already installed the whole Ansys package.

When I used the parallel option in the Fluent, I received a message that the license is restricted to 8 cores only and we have 32 cores.

Sounds like you have a wrong license key or you have less licenses than you though... What do you have? A single HPC pack?

I have Ansys 14 but not HPC pack

But you say you have 32 licenses... how does this work without HPC?

No. I have 32 cores on dual processor.

I don't get it. Your hardware does not seem to be the problem. It's your license. Obviously, your license thinks it is for 8 cores max. You say, you don't have an Ansys HPC license, which I don't understand, because as far as I know, HPC is the way to get an 8 core license. What kind of license do you have? It doesn't seem to be a standard Fluent license, because that runs just on a single core.

I guess you have an academic license. Some academic licenses have this limitations.

RodriguezFatz March 21, 2013 04:46

Don't they have 4 core max? At least in Germany...

Academic licences do have multicore computation enabled. I have used upto 4. It seems that his licence is only for 8 cores. I know ANSYS sells the HPC pack in multiples of 4 (4,8,14) etc.

I remember that at university we could only use 4 processors at one time although our clusters has nodes with 8 and 16 cores.

All times are GMT -4. The time now is 10:51.
