wave generation in star ccm+
 

I am doing a wave structure interaction problem in Starccm+ my problem is that after some iteration my total wave surface is going down (i.e. water level) even i keep the release time of the structure is around 8 sec because i want to see the effect of waves .
My boundary condition is 5 are velocity inlets and one is pressure outlet according to the tutorial.
please can any one suggest me something .

Do you still have the problem or did you figure out?
