Questions about ReTheta & Gamma setup in airfoil calculation

kevin.pku · December 4, 2018, 22:53

Dear all,

I am calculating the NACA 64312 airfoil. The freestream velocity is 50m/s, the turbulent intensity is 1%. I use the Komega SSTLM transition model for calculation and my setup for U, k and Rethetat are shown in the attached figures. Unfortunately, the calculation fails. There may be some errors in
my setup. Could anyone help me? Thank you.

Try correcting the fvSchemes and fvSolution, there is a case in wolf dynamics tutorial where he has done naca0012_transonic, I used those schemes and solution and it worked for me. Best of luck
