Hello,nYes, this looks like a convergence issue to me. This could be because of several reasons. nWhat is your mesh quality? nAlso, how large is your time step and what is your Courant number. Please try to reduce your time step to see if you are able to obtain a better convergence. nAlso, make sure your boundary conditions are physical.nThank you.nKarthikn
