I am having doubt, if any one kindly help me to clarify those, it will be very useful. I have spherical mesh domain and at the center I have a plate and I wish to compute aerodynamic coefficients at different conditions. I have to use compressible flow. I am using freestram as BC for p and U, but not sure as I am getting diverged. Also I see negative k and epsilon (which is wrong). How can I calculate k and epsilon for farfield. Thank you very much. And happy new year. Bye
