Ocean Wave Model with FLOW3D
 

Dear all, I'm using FLOW3D to model ocean wave over submerged breakwaters / artificial reefs. When I try to plot water surface time history, It seems slightly accumulating...even when I remove all obstacles (such as generating wave in a flume) Is this commonly happened in Finite Volume Methods? (I'm a newcomer in VOF world) I wonder if somebody here has experience with modelling ocean wave using FLOW3D would share their results in this forum.. or assist me... Thank you in advance Haryo
