Hi everyone, I am beginner in Fluent so want some advice for flow past rear wing of f1 car associated with vortex shredding . I am facing difficulty to choose a correct model for convergence.
First problem is my base for unsteady transient analysis that is steady analysis for which i chosen k-omega sst (with cuvature correction on and second order upwind scheme for all variables) is still not converging for 1000 iterations(while same geometry model with less complex features which produces low vortex shredding converges below 170 iterations). Flow speed-83m/s
Second problem is my Les wale model is also unable to converge.
Please suggest
