hi guys

right now i´m making my diploma thesis and for that reason i´m simulating a Pressure control valve. first i made some laminar calculations and everything was fine but now when i turn the k-epsilon model on the calculation starts good but after some time the courant number rises up infinitely high within 4 or 5 iterations and stops. i tried to change the initial value for k but only the time the calculation stops changes. could somebody please tell me some hints or how to set the initial values for k and epsilon. i´m looking forward to hear from you guys.

greetings Simon
