Hello
I am trying to model horizontal wind turbine to show tip helical paths and wake. The problem here is that, i must make grid very smooth. I can't make that for whole domain or by periodic rotating boundary conditions because of out of memory problem. I need to divide fluid domains into multi-zones and solve each domane individually. I have one inlet and one outlet, by which boundary conditions should i make the interior faces between domains. I need to make the outlet of first domain the inlet for the second domain and so on. Any one help????
