gxu2 is on a distinguished road
I use udf of stokes wave to be imported into fluent as the inlet boundary, VOF method is employed, bottom and top are no-slip wall, outlet is outflow. I found one phenomena that the wave dissipates through the flume and disappears at the outflow, Could you help me how to modify this phenomena, thank you very much!
