water depth descend in the numerical wave flume

G++ · April 1, 2015, 06:12

Dear all:
I am intend to build a numerical wave flume with a porous structure in the end.Then a linear wave was generated, however, after some runtime ,the volume of water in the flume decrease and the water depth descend ,who can tell me why?

What BC did you apply?

linear wave in x Max,wall in x Min,x denotes the direction in which wave propagate.

I do not sure the why the case occured. Would you try to change Xmin to wave, and Xmax to outflow?
