wave force problem

hello everyone:
now I have a problem about wave force.when I simulate a wave height is 0.2m and the diameter of cylinder is 0.3m,the force of the cylinder is well output and the result is pretty good,but when I change the wave height to 2m and the diameter to 3m, the result oscillation and the wave force is wrong, I do not know why?who can help me? thank you for advance!

Which wave model are you using? Can your wave be considered still linear even with 2m height?
What data are you comparing with?
