• multiphase/interDyMFoam/RAS/motorBike (fails at omegaWallFunction)
• multiphase/interFoam/laminar/vofToLagrangian/lagrangian* (the logic for precursor case still fails)
• compressible/rhoSimpleFoam/angledDuctExplicitFixedCoeff (invalid rhoThermo type)
• compressible/rhoSimpleFoam/squareBend (invalid rhoThermoType)
