Hello,
I have a model with 10 million cells, if the solution takes 3000 iterations to converge, how do I estimate the computational resource requirement (number of cores, memory RAM) so that I get the solution in n hours (say 12)? Thanks Kind Regards |

A typical segreggated solver usually takes about 0.6 - 0.8 GB per million cells. So max you would need is 10GB to run this case. Which solver are you going to use. |

Thanks Arjun, I plan to use Numeca or Fluent.
