haku88 New Member Join Date: Jul 2013 Posts: 1 Rep Power: 0	Hello. I was generating linear wave (H=1 m, T=8 s, L=100 m) in the water tank (850 x 50 x 40, x, y, z(height)). I generated mesh near the sea surface with the maganitudes of 0.3 m and wave started to damp out continusously when I simulated for 24 s. wave damping was set to operate at the end of the tank. I checked the similar questions before me and it seems to be mesh problem..but I wonder that someone's wave simulation was successful with 0.6 m mesh size with wave height 1m, T=4s. How can I fix this problem ? please help
