Hi Dinesh, Thanks for your interest in PyFR.
Currently PyFR only has a compressible solver, but we seem to get good agreement with incompressible data by running with Ma = 0.1-0.2. You would probably want to try a characteristic BC (char-riem-inv) at the domain outlet in the first instance. We are working on adding a true incompressible solver at the moment.
