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. |

For cheapskates like me that are interested. Dell inspiron 580, i5750 6GB ram, 1 terrabyte hd, 1gb graphic card, 21.5"
$620 http://reviews.cnet.com/4504-3118_7-0.html?id=33775568&id=33975471 I figure I can always upgrade motherboard if I need more than 8gb memory. Brian |
