Arbitrary Lagrangian-Euler method with FDM?
 

Hi, all

How can Arbitrary Lagrangian-Euler (ALE) method be realized in Finite Difference Method? I have read some literatures, all of them use Finite Volume Method. why?

also is it possible to satisfy the so called "Geometric Conservation Law" in finite difference method? it's said that FVM has advantage in maintaining conservation law.

are there literatues about the ALE methods and GCL in FDM?

thanks, regards
