Hi Stefan,

I have 23k elements and an lx1=11, so I am guessing my resolution is reasonably good (32 Mil Nodes) . As regarding the boundary conditions, yes I do add some divergence at the outflow. I am running it at CFL of close to 2 with 2nd order time stepping. Would you recommend lowering the Courant to say 0.5 ? Even though the warning pops up, I don't see any crazy stuff happening in my flow .
