Default combining fluid structure in parallel

Hi foamers,

I am working on a case that requires me to combine a continuous fluid structure (say a droplet) separated by a processor patch. To do this, I need to know the cell IDs of each processor in order for me to combine such a fluid structure. However, the cellIDs of the decomposed domains are not consecutive. Therefore, I am wondering if I could renumber the mesh in order to make all faces, cells and points consecutive in all sub domains. To make this easier to understand, suppose we have a square computational domain with a cell number of 50000. In serial mode, the cellIDs are numbered from 1 to 50000. In parallel mode, as the domain is decomposed, each domain has their unique set of cellIDs starting from 0. So for processor 0, the cellIDs are from 0 to 12500 as the same is for other domains.

How can I make cellIDs for the above case go from 0-50000 for a decomposed mesh?

I very much appreciate your help.

Best regards,
Carlen
