Hi all !

For my personal project, I am trying to implement the wall film phenomena into an engine process simulation.

My starting points were the solvers reactingParcelFilmFoam and dieselEngineFoam. Basically, I am trying to build a kind of "dieselEngineFilmFoam".

So far, (I think) I succeed in adding the surface film modelisation into the dieselEngineFoam code. The problem is about the mesh moving.

--> FOAM FATAL ERROR:
mesh flux field does not exists, is the mesh actually moving?

From function fvMesh::phi()

I was thinking to modify the class engineMesh and layeredEngineMesh. Now my question are :

Is it possible/feasable to move the mesh from 2 different boundary layers that are located in 2 different regions ?
Are there easier and better other ways than the way I am doing ? For instance, are there some kind of utility that can help me doing what I want to simulate without modifying anymore the code ? (moveEngineTopoMesh, moveMesh and so on...)

Also, my big question is : How do I move the mesh from 2 different boundary layers from 2 differents mesh regions ?

PS : I am now working with the geometry from Kiva (tutorial engineFoam).
