I am using a C-grid from here to analyze the NACA 0012 airfoil using Cradle's SC/Tetra. I am having some trouble setting the boundary conditions. What BCs should I use? For what I have already tried, some regions of the grid develop a very high pressure and others have a very low pressure. (This only happens when the angle of attack is non-zero, and in case it matters, I am simulating the angle of attack by varying the inflow direction).

I hope somebody can help me! Thanks in advance.

P.S. I'm obviously new to this forum and hope to become more active once my work gets more difficult.
