Recently, i'm using the CompressibleFlowSolver by setting the CFL instead of deltaT for running my simulation. However, if i run the simulation with this configuration, it happens that the simulation is completed in only one step and i'm not able to figure out why. I have attached below the screen of my configuration below (SESSION_NEK) and also the output of the simulation. Someone have suggestions? Thank you!
