Hi,

I want to simulate two fluid regions which should be coupled with a mappedPatch. The reason is that I want two simulate the different regions with different turbulentModels (RANS and LES).
If I set up my boundary files of the two regions with:

    oldInternalFaces
    {
        type            mappedPatch;
        sampleMode      nearestPatchFace;
        sampleRegion    fluidRANS; // respectively fluidLES for the other region
        samplePatch     oldInternalFaces;
        nFaces          176;
        startFace       61548;
    }

and for my boundary condition (i.e. U):

    oldInternalFaces
    {
        type            mapped;
        setAverage      false;
        average         (0 0 0);
        value           uniform (0 0 0);
    }

I get the error:

--> FOAM FATAL ERROR: 

    request for volScalarField mut from objectRegistry fluidLES failed
    available objects of type volScalarField are
0()

Any hints? Thank you.
