I need assistance in simulating the turbulence created by wave impact at the toe of an embankment support. Beach angle, incoming flow and gravity flow must be taken into account. Any assistance will be greatly appreciated.
CFD can simulate turbulence, but what specific results do you want to see?
The multi-phase free surface VOF solver in Caedium can simulate water and air interaction, for a tutorial see "Transient Water and Air Flow in a Tank".
If you are not familiar with CFD then I suggest you start with some basic tutorials to see how to configure geometry, physics, and results, e.g., "Incompressible Flow Through a Pipe into a Box".
