Hi Peter, you were right, time step was calculated by using delta x, should have used delta y since this is my smallest cell direciton. With a time step of 1e-08 no NaNs occur.
But next question arises. What do the residuals exactly show? I see that rhou rhov and rhow are printed, just wondering about the absolute value, since this is around 1e+06 for all values. Are they normalized in a strange manner? On Monday, December 19, 2016 at 11:44:58 AM UTC+1, Gabriel Axtmann wrote: > > Hi Peter, > I use a time step of 5e-05, which equals in CFL<0.3.
