Hello all,

I posted this in hardware as well:

I am a new graduate student modeling wind turbine blades. I am currently simulating Fluent on a dell xsp 435mt system. The simulation is run in parallel with 2 processes. The sim. usually requires 4-5 gigs of memory and cpu runs around 40%, and takes 8-10 hrs to converge. The dell has a 4 core processor with 8 threads, does this mean I can run 8 or 4 processes to speed up sim. time. We have an academic liscense, would that limit the number of processes?

Also have permission to buy a pc for CFD and wind tunell apps in the new lab, with bugdet around $1000. Any recomendations?

Also am thinking of upgrading PC at home for CFD, with a budget of <800$

Thanks

Brian

Can you assemble a pc by yourself? We did that and we could get a really nice desktop, way cheaper than preassembled ones.

Intel core i7 - 300 $
DDR 3 Ram 6 B - 200 $

For the rest 300 $ you can fit in the rest of the parts.

I will look into self build now. I get a hp student discount and can get HPE- 108t for 1250$ with the i7, 9g ddr3, !tb, 23 inc monitor, seems hard to beat

for myself hp p6380t with Q8300 processor 6gb ddr3, 640 gb hard dr, 20" monitor for <$700.

Please comment if anyone has experience with these systems.

thanks

For cheapskates like me that are interested. Dell inspiron 580, i5750 6GB ram, 1 terrabyte hd, 1gb graphic card, 21.5"

$620

I figure I can always upgrade motherboard if I need more than 8gb memory.
