Is it possible to access the information of the neighbour cell across a processor boundary? I know how to do that if both owner and neighbour cell are on the same processor, however, I cannot do that if otherwise. I'm sure OpenFOAM swaps data on the processor boundary using syncTools and the like, but I don't know how to employ those functions in my own solver. What I want to realise is to know the value of alpha1 of the neighoubur cell across a processor boundary while I have the information of the face shared by its owner cell and neighbour cell, and I know the owner cell on the current processor. Therefore, I need to know the cell number of the neighbour cell on another processor. I am not sure if I can do that on the solver level of code. Could you share some hints on this please? Thanks for your time in advance.

I've moved your post from the thread where you originally posted http://www.cfd-online.com/Forums/ope...-problems.html - since it was a bit out of context... i.e., this is a programming question.
After a very brief Google search:
site:www.cfd-online.com openfoam access neighbour across processor
Beyond this, I never needed this myself, so I have no idea how it can be implemented

I am also very interested in how the neighbor cell information is accessed during the parallel for cells with inter-processor interface. Have you found the solution?
