Hi everyone,

I am trying to simulate internal waves due to vertical density gradients in a tidal inlet sill.I intend to use the Boussinesq approximation, but am unable to find a way to specify the density as a function of depth. If anyone could throw any light on how to do this/how best to use the Boussinesq approximation in FLUENT, it would be of great help.
