manely is on a distinguished road
Hello,

I use the Reynolds SSG model to compute Reynolds stresses in a two-phase stirred tank (water and air). To check the grid dependency, I used three untructrued grids with number of nodes 1,3 M, 5 M and 21 M. During simulation with a parallel cluster (Linux, 64 bit. 8 partitions and 4 CPU's pro partition) I received overflow error. Now I'd like to know how much memory I actually need to resume the simulation and running it till the convergence (EMS Residues under 10E-4). Does somebody know here?

Many thanks, Manely
