hi
1. I am running fluent for external Aerodynamics. I got converged solution for coarse grid.Whin I refined the grid to satisfy Y+ criteria the residual is not converging Even the Force Coefficient is also oscillating. 2. Even though Y+ value is as high as 500. I am getting reasonable match in Force coefficient values foe Spallart ALLMARAS Model. Is Y+ is meaningless? please answer me. Thanx. |
