Exchanging fields across processor boundaries
 

Hi!

To parallelise a home-brewed (OpenFOAM-) code I have to send some fields across processor boundaries. Specifically, I need the cell centers of the faceCells at the processor boundaries and the values of a volScalarField stored at those centers. I have begun to code this but probably it is already implemented in OpenFOAM, isn't it?Any advise how to send these fields is welcome!

Thanks for your help!

The processorFvPatch / processorPolyPatch classes already do this for you.

Take a look at the sources.

Hi Sandeep,

thanks for your reply!

I know that the processorFvPatch / processorPolyPatch classes would normally do this for me. However, I have implemented a few methods which step out of the normal FVM-framework of OpenFOAM, it's a finite differences method which draws heavily from neighbour relations in specific directions. I have written my own code to describe these relations and would like to extend it to parallel computations. Thus, I have to exchange the fields mentioned above by "hard coding" the data exchange in my code...

Thanks again!
Roland
