Hi,

I am looking for lists/references/methodology on how to account for moving objects in the computational domain.

For example, what methods are used account for the mouvment (closing/opening) of valves in automotive engines.

Thanks for helping. jdc

You should look into the Arbitrary Lagrange Euler formulation (ALE) in this formulation you have a grid arbitrary velocity field that is independant from the fluid/material velocity field. We use ALE to perform valve opening and closing. You can visualize examples on our website www.mcube.fr

Other methods involve a re-computation of the boudaries at each time step. I am not a specialist of those.

Regards,

Dimitri.

Thanks. Julien
