@Apollo_Racing: It seems you did not look at examples of successful simulations. Your current geometry is a culprit. When I’ve seen it, I thought it was a clogged vacuum clear tube simulation.
You simulation domain is too tight.
Result control > Forces and moment coeff > Free stream velocity should match the Input flow velocity.
You would need Initial Foam initialisation set to ‘yes’.
You can notice, that Force and coefficient plot looks quite good till ~200 simulation steps:
Running it for more, is a waste of resources. You should stop the simulation in that case, mend the setting and restart a new one.
Thank you so much, this been such a bother to me it’s great to get some help. But I can’t seem to find where it says initial foam intialisation
Should be in Simulation control > potential foam initialization.
perfect thank you
