Ultimate Machine Build - CFD - £3-5K Budget

Hi

I'm looking at spec'ing a machine for cfd (Ansys CFX). Looking for raw speed for mathematical calculation 12-16GB ram spec...£3,000-5000. Dont worry about graphics card as that'll be a quadrofx 3500

I'm a bit out of touch with the latest and greatest, can someone please help me spec a machine?

Thanks

hi all

thanks for talking the time to respond. right, I'll try to answer all of the questions!

We do indeed pay per core. We have licences for up to 5 cores only - ie any more cores is a waste. (its cores too, not cpus)

Time scale..this week ideally. I've been given the red light at work...that doesnt happen often!

Noise etc...would be better if lower noise..watercooling?

Would prefer it if somebody else assembled but I've done it myself before, and there are plenty of people at work who could also do it.

Budget is £3000-5000 dont need a screen with that.


The way the software works is that a CFD study is broken into various stages:

Meshing>pre-processing/setup>Solver>post processing

Only the solver stage can use multiple cores, for meshing etc its all on one core so a fast (single core) is prefferred.

Regarding Xeons etc. I currently sue a Dell Precision T7500 with a single 8 core xeon @2.66Ghz cpu with 16GB ram. Its quick but not as fast as I would like. I was hoping that the i7's would be faster.

Any more input is really appreciated. hopefully this response helps!
