Hi everyone,
I have a problem with modelling free surface of ponton moving by Ansys Fluent (image attached).
Can you explain for me why bow wave is very high but side wave is zero and stern wave is very low?
I think, have an error in my simulation.
Other problem: after solution is converged, appearing reversed flow on pressure-outlet and resistance increase dramatically?
Thanks for supporting!
