I'm running external heat transfer sim and everytime I make some changes to the model (add some ventilation openning, rib etc.) than the computational domain "returns" to its probably default size?? and I need to manually set desired size of it (bacause it's a bit different to run sim with 750k or 3,5M cells ) ....is that normal state or am I doing something wrong?? Or is there a way to fix comput. domain sitze??
thanks for advices..
