Hi Rob, I have another question. When I simulate high velocity (10 m/s) for let's say 5.5 m height water, I get weird results.

Density after initialization (red water, blue air):


Velocity after initialization (10 m/s for the water 0 m/s for the air):


After a lot of iteration water interacts with the structure, but a weird wave is created upwards as seen in the following pictures. Therefore, water height ends up being greater than specified in the inlet. It ends up being like this (not finished running simulation):


Also, the velocity in front of the structure is reduced from 10 to 7 … Drag and lift coefficients are still computed with a velocity of 10 m/s but I don’t think this results are right…
