Small cluster configuration for pump simulation at CFX

Nevel · January 29, 2010, 08:17

Dear colleagues,
could you please recommend a configuration of workstation or small cluster for pump simulation at CFX?
The pump is centrifugal and single-stage with volute and diffusor.
Steady-state (frozen rotor) and transient simulations.
Cobination of hexa and tetra/prism meshes.
Whole model number of cells is about 8 milions.
Required time for 1 iteration is about 100 seconds.

Thanks a lot for your replies!

You can go for an Intel cpu type W3570, W3580, W5590 or I7. The W35xx types support up to 24 GB memory which is enough for your application. Go for DDR3 1333 Mhz memory. I'm not sure, but I think 6-8 GB is enough for 8 million cells.
Complete the system with a fast hard disk, some thing like a 15K rpm SAS or SSD. Instal your applications on this fast disk, and use the fast disk as working directory for your CFD analysis. For data storage you can get a cheaper 7.2K rpm HDD.

I think it doesnt make a big difference if you go for HP, Dell or something else. As long the components are good.

If your software can run more than 4 threads, you can look at a double quad core cpu.

At the moment I'm configuring a workstation for the same kind of analysis you would like to run. I looking to a HP Z400, Z600 or Z800 with the W3570 cpu and 8 gb of DDR3.
