Hi everyone.
I have gone through the code for interFoam ( OpenFOAM version have the dynamic mesh capability already incorporated into it) and found a particular code snippet :

// Do not apply previous time-step mesh compression flux if the mesh topology changed.

 if (mesh.topoChanging())
               {
                   talphaPhi1Corr0.clear();
               }

I don't see this code in foamExtend versions of interDyMFoam. How does foamExtend go around this? Or specifically how does it help with the simulations? This was introduced in OpenFOAM v5 and higher if I am not wrong. ESI OpenFOAM derives this from createAlphaFluxes.H which is in applications>multiphase>VoF>createAlphaFluxes.H

// MULES Correction 
tmp<surfaceScalarField> talphaPhi1Corr0;

I am not able to go deep into the numerics. From the documentation, however, it shows that this is used only in compressibleInterFoam family. But the codes are present in incompressible i.e interFoam as well.

With regards
