i am using the v9.3 flow 3d. i am using the wave boundary from the one site and the outflow from the other. the water volume is always be less. the water is going out of the outflow and doesnt come in from the wave boundary. so the water height after some wave periods is zero. whats the Wrong??

Hmmm. What if you try a pressure with the fixed free surface height, instead of the outflow BC? How many wave periods are you simulating?

Good idea, Aginor. That's exactly what this function is for.
