Crash after redistributing the mesh- interFlow

[Ananth-Narayan-IITM]

Hello Henning,

I have recently came across the interFlow solver across two repositories (VoFLibrary and TwoPhaseFlow). I am trying out this two phase problem (Hysing benchmark problem) with AMR, while redistributing, the solver crashes. This happens with both the repo solvers iof interFlow. I am using OpenFOAM 1812 and find the case file

e0R16.zip

The error I got is,

PIMPLE: iteration 1
Selected 117653 cells for refinement out of 130305.

Is there anything we need to modify the solver for dynamic mesh update. What I feel is that the error occurs when the Uf is being recomputed, as the mesh size doesn't match causing the solver crash. Please let me know if I am missing out anything.
