Subject: [PATCH] BUG: potential fix for stale fvMesh addressing - see #1956
Failures shown in interFoam cases were found to be a result of stale ldu
addressing in fvMesh. Potentially delete lduPtr_ alone, but likely safer to
clear all addressing:
// deleteDemandDrivenData(lduPtr_);
clearAddressing(true);
