Nettet15. feb. 2024 · Hi, I'm running a case in OpenFOAM (v1606+) where I have trouble with solution convergence and bounding of k and omega. The case is a oscillating cover (looks like a 2D cut of a bowler hat) in infinite fluid. There is no inflow or outflow, just still water and the cover oscillating in the y-direction. The simulation is obviously transient. chassis liner 7 tower frame machine
