[Lilia Carlo]

Good morning everyone,
I'm working on a two-dimensional model in Fluent, in particular the domain of the sea with genarate waves by wave maker and a REWEC (Absorber with oscillating column operation OWC having a hole at the top where a turbine will be inserted) a the end of the domain, however the waves are reflected on the wave maker in fact the wave height continues to grow during the simulation, you know how I can fix it?

Setup

VOF
Boundary conditions:
Wave maker: wall with dynamic mesh
REWEC: wall
Outlet turbine: Pressure outlet
Air: Pressure Outlet

UDF dynamic mesh:
#include "udf.h"

DEFINE_CG_MOTION(wave, dt, vel, omega, time, dtime)
{
vel[0]=0.0799564943*2.775744221*cos(2.775744221*time);
}

Attached the images of the domain (domain) and the free surface (pelo1) in correspondence of a probe near the wave maker.
