Hi everyone,
I'm trying to adapt the tutorial "motorBike" which contains kEpsilonSST turbulence model to my own case "the Backward facing step". I'm not running in parallel. I just implemented the classical files to run a computation. The computation starts and the residuals look good except "time step continuity errors" which crash. I don't understand where the problem is. My boundaries conditions seem good. I get this error in the terminal. Code:
