I am carrying out transient simulation in fluent. Turbulence model used in k-e with scalable wall function. Velocity inlet condition is used and static pressure outlet condition is used.
Time step size is 0.002 giving courant number around 10. Absolute criteria for convergence of residual is 10^-6 Under relaxation factors are : Momentum 0.5 TKE 0.5 I am not sure if the solution is converging or not ? Please help me in the following : |

It's a very simple domain and setup. What could be affecting convergence? I changed the relaxation factors right away . Does this affect convergence ?
Thank You Last edited by raunakjung; February 17, 2017 at 20:02. |
