Replies: 12 can t reach steady state chtMultiregionFaom Views: 3,846 Posted By mabinty can t reach steady state chtMultiregionFaom Dear all! I m about to simulate half of a symmetric 2D 1x1m2 domain, with hot air entering from an inlet in the floor. The sides are open (ambient air can enter). My interest lays in the heat...
