    Hello,rni’m developing a 3d lid driven cavity case, but i’ve some problems with the code, the density diverges. So where could be the problem? I can’t understand it…( I imposed omega=0.3158 Re=4.5 xDim=yDim=zDim=61 uMax=0.1 nu=0.8888 tau=3.1666 Ma=0.1732)rnrnThanks for the help.

    Hi,rnrnOmega is quite small. I propose to try with smaler uMax, e.g. uMax=0.01.rnrnBest regardsrnMathias
