Hello,

I know that this question is posted every now and then on the forum, but... my hardware knowlege is so poor that I need a specialized answer... I am planning to buy a new workstation for my CFD simulations. I need some hints, some suggestions and some good advices on how to select it.

Usually, I run steady, incompressible and turbulent simulations (simpleFoam), on really complex geometries (1 million cells at least). I would like to get into:

• unsteady, incompressible and turbulent simulations, with dynamicMesh -> pimpleDyMFoam
• steady, incompressible and turbulent simulations including heat transfer -> a new solver should be made on the basis of chtIcoMultiRegionFoam or conjugateHeatFoam
• unsteady, incompressible and turbulent simulations including heat transfer -> a new solver should be made on the basis of conjugateHeatFoam

Of course, these are for geometries as above, or even more complex.

Here come my questions:

• what is important when selecting a workstation for CFD purposes? Processors, memory, hard disks?
• what are the standards (the minimum requirement) for the tasks described above?
• what is the suggested configuration instead?

Any comment is really appreciated.
