It is worth the money?

Jaume Batlle Sep 2, 2014 5:41 AM

Hi guys,

Normally I work with flow simulation with small problems that can be easily solved (warm up air, velocity...). But now I need to simulate an huge part of the machine I'm working on (8x5x10m, with 8 fans, humidity and heat conduction). The problem is that the solver crashes (efdsolver stops working) before it has finished. I told my boss that probably we need to upgrade our workstation to something more professional (currently we have a 32 Ram, GTX 770, I7...) but i saw on the internet what some workstations like HP Z820 (HP Z820 Workstation - ) It is woth the money? I will be able to resolve this kinds of problems with this workstation? I need to be sure before buying it.

Thanks you!

how many cells?

what version and service pack?

do you know why the solver is crashing?

i have a laptop that i solve most of our consulting projects on that is equivalent to your computer (except with a better graphics card) and it solves pretty large problems

i'd investigate the crashing first. if you are running out of resources, ok, upgrade. but if your geom is bad, causing the solver to crash, fix that first.

  The crash as I said is that EFDSolver stopped working. I will uploead 1 picture. I tried to find a solution for this crash but i found nothing and I have no idea how i could solve it.

    my guess is you have bad geometry or a setup issue
