I need to some help in deciding adaptive CFL parameters for my case
It is a 3-d, supersonic, viscous, steady, turbulent flow case with flow in x direction, RANS simulation. I have given value of CFL=0.5, Euler Implicit scheme, FGMRES linear solver with ILU preconditioner. My solution initially converges for some iterations then starts to diverge. I have given parameter CFL_ADAPT=(0 , 1.2, 0.5, 100 ) respectively based on given template and tutorial cases. I am not sure about these parameters. Can anyone give me some more idea about adaptive CFL and how I can modify these parameters for convergence of my results? Also, can we print CFL value for each iteration in our console as screen output just like residual? I am new to SU2 and CFD. |
