CFD Online Discussion Forums - Simulating VoF with NNC and AMR in openFoam

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:

Code:

--> 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!
