DEFINE_CG_MOTION(wave, dt, vel, omega, time, dtime)
{
vel[0]=(0.30823)*((1 - exp(-0.417*time))*1.0472*cos(1.0472*time) +...

Ok. In the simulations, the sinusoidal movement only Its seen in X=0, from the mobile wall, but with X>0, the movement is zero, there is not height of the wave. I will try with both methods and I...

Any help would be appreciated:

I am using FLUENT to model a regular wave tank with linear theory and dynamic mesh in 2D. I am using a VOF multiphase model (water and air), with transitory regime....
