help me for"wave maker"&"wave absorber"

bestrcsekhar

hi,

i,modelled the wave tank of dimensions 300mX30m with a water depth of 20m, using fluent software.

now i have to apply the boundary condition i.e "wave maker" and "wave absorber" at both ends using "user defined function"

i have to develop a wave of amplitude 1 & 2M using piston motion. so help me to find these boundary conditions.

with regards sekhar
