Good afternoon, I am trying to do a simulation of half wing (symmetric) for my thesis with the following conditions.
U = 40 m/s L = 0.2m mu = 1.5 x 10^(-5) m^2 s^-1 rho = 1.117 kg/m^3 I = 3% With these same conditions and mesh, I have succesfully solved the problem with no turbulence and with Spalart Allmaras model. However, when I do a K-e model, the simulation diverges really fast, like in 12 iterations, and I do not know why. I attach a folder with all my files in order to let you check them out. I think that the problem is on the initial and boundary conditions, because if I just let the relaxation factors in 0.05 it still does not converge. https://www.dropbox.com/sh/4iu3d75i1...G74gMY4qa?dl=0 Thank you very much! |
