Modify NS eqns for moving body -- CFD Online Discussion Forums

Northstar Guest Posts: n/a	May I know if I need to add linear acceleration terms like mass X acceleration into the momentum eqn if I am going to model a moving body. the grid will stay with the body and move together with it up and down sinusoidally ? If so, what is the term exactly that must be added? thank you.
