But the issue is convergence can be obtained from 0 degrees till 15 degree but after that convergence doesn't occur. I've tried increasing the number of iterations but nothing happens.nReference area for my wing is 0.03m2.nI've tried other turbulence models also but this time at any angle of attack I couldn't get a converged results.nPlease help to resolve this issue.n
