Good HARDWARE specification for ANSYS ICEM

Vijay1996 · February 22, 2019, 02:14

I'm a beginner to CFD , i'm carrying out COLD FLOW ANALYSIS for IC Engine
on A PC with
INTEL 6700 3.2 ghz 8core
32 GB RAM
6gb GRAPHICS Geforce 1080

the point is that it takes computation time of around 4 days
is there any recommended specification to ease the process of solution.???

Let me try to untangle this:
ICEM is a pre-processing tool. I assume you are not running simulations with it. So which software are you using?
Then what you do sounds like a transient analysis with moving/morphing meshes. It is not unusual for this kind of simulation to run for several days, even on more powerful machines.
What cell count are we looking at? Have you made some attempts to cut down the actual computational work? E.g. simplifying geometry, doing sensitivity analysis for cell size / time step size / number of inner iterations if applicable...
Then how are you running this simulation? Batch mode? or via GUI? Are you saving a lot of data during the simulation? Does your case fit into memory?

Finally, before recommending something better we would need an approximate budget. Obviously spending 10k would get you further than spending 2k.
