Hi Bukreev,
Thank you for your reply and confirming the dynamics and BC. I did not use a higher lattice velocity because I wanted to be conservative on the Mach Number side. Ma correspond to the characteristic velocity is 0.044 and maximum velocity goes 1.3 times the characteristic velocity. That said, a slightly higher lattice velocity gives similar result.
