Hello all,

Need some advice.

I currently use CFD for turbomachinery, with models little more than half a million cells (one blade passage steady state) and the solution converges in about 3 hours (2000 sweeps) on a 6 core PC. I am about to use several full geometry model with about 10 million cells for both steady and unsteady computation. I am sure that I need additional computational resources.
I am planning to expand the computational resources so that I would be able to see the solution within 12 hrs.
I am confused what to get, single or several high end PC/work station or a small cluster??

1. which would be suitable for my case?
2. which would be better on a longer run for lesser CFD turn around times?
3. which is more advantageous in terms of maintenance, flexibility and cost effectiveness?

Kindly share your expertise

Kind Regards,
K
