Hi, I'm currently working on simulating Volume of Fluid (VoF) in OpenFOAM using NonConformal Coupling (NCC). However, I've run into a roadblock with the following error:

--> FOAM FATAL ERROR: 
The start face is not defined for a nonConformal patch with a non-zero number of faces

    From function virtual Foam::label Foam::nonConformalFvPatch::start() const
    in file fvMesh/fvPatches/constraint/nonConformal/nonConformalFvPatch.C at line 98.

FOAM exiting

This error occurs when I use MPLIC for div(phi,alpha) in my fvSchemes, everything works well with interfaceCompression.
The thing is I can't employ Adaptive Mesh Refinement (AMR) with interfaceCompression.

Has anyone encountered a similar issue or have insights into resolving this?

Thank you for your help!

Hi Chuffa,

see the answer from Jan in this thread, NCC and PLIC/MPLIC is not compatible:
PLIC and 2-1 constraint
