Hello All,
I'm beginner in waves2foam and trying to create a 2D stokes 5th wave.

As far as I know, the relaxation at the outlet forced to kill the waves like sponge layer.(where the velocity vector is set of 0 and based on the position of the still water level.)



but what I'm trying to do is force the outlet to follow the theoretical formula as inlet relaxation zone.



If anyone knows this problem, I'd really appreciate it if you could let me know.
thank you.
