Subject: [PATCH] tutorials/multiphase/interFoam/RAS/damBreakPorousBaffle:
 Updated porosity coefficients

The implementation of the porousBafflePressure BC was incorrect in OpenFOAM-2.4
and earlier and corrected during the turbulence modeling rewrite for
OpenFOAM-3.0.  This update introduced the density scaling required for the
definition of pressure in interFoam which requires the porosity coefficients to
be reduced.
