Hello,

I am trying to generate a list of global cellIDs for a cellSet using local cellIDs of a decomposed case.

I have tested my code for two cases; cavity and 1D straight channel.

Code:
        globalIndex globalNumbering(mesh.nCells());
        word cellSetName = "b1";
        cellSet c1(mesh, cellSetName);
        labelList channelID = c1.toc();
        labelList gloProc(channelID.size());
        labelList locProc(channelID.size());

        for(int d=0; d<channelID.size(); d++)
        {
                const label globalCId = globalNumbering.toGlobal(channelID[d]);
                gloProc[d] = globalCId;
                const label localCId = globalNumbering.toLocal(globalCId);
                locProc[d] = localCId;
        }

        Pout << "Local Lists on all Procs " << locProc << nl;
        Pout << "Global Lists on all Procs " << gloProc << nl;
Here, the global cellIDs generated from local do match with non-decomposed cellIds (i.e, in constant/polyMesh/sets/) for only the channel case.

They do not match in any way for the cavity case..!!

Am I doing something wrong, or this might be a possible bug.

Any suggestions..??

Thanks.

Ps: I am using OFv1806
