Hello Everyone,

I am currently working on Fluid-Structure Interaction problems which needs me to use Arbitrary Lagrangian-Eulerian Meshing Techniques. I have been through a lot of literature and still haven't found any reliable source which can help me code it by myself. I need some algorithm for that matter (probably in 2 Dimensions). I have just joined CFD-Online and I don't have much experience here too. I would appreciate any codes made by anyone on which I can perform reverse engineering and understand it.

I need some source where I can learn ALE without much complicated equations as found in almost every open-source and literature.

Thank You in advance.

Rather than reference literature that specifically uses the term "ALE description of motion", you may simply want to take a look at a fluid mechanics text which expresses the conservation equations of mass and momentum for moving control volumes. This is essentially the same thing as ALE (mesh/CVs can move independent of the fluid) but the presentation is more palatable. I recommend White's Introduction to Fluid Mechanics or Munson's Fundamentals of Fluid Mechanics.
