This provides more flexibility in specifying the allowed internal and boundary
extrema.
For driftFluxFoam and other settling problems it is beneficial to set the
boundaryExtremaCoeff to 1 to allow rapid accumulation of the partials on the
bottom wall (which was the previous default behaviour) but this is not suitable
for many Euler-Euler cases for which a uniform etrema coefficient is preferable,
either 0 or a small value.
Now by default boundaryExtremaCoeff is set to extremaCoeff which defaults to 0
which provides the behaviour before
OpenFOAM-dev commit cb2bc60fa5
and the driftFluxFoam tutorials have been updated adding
boundaryExtremaCoeff 1;
to the MULES controls in fvSolution so reproduce the previous behaviour.

About OpenFOAM
OpenFOAM is a free, open source computational fluid dynamics (CFD) software package released by the OpenFOAM Foundation. It has a large user base across most areas of engineering and science, from both commercial and academic organisations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics.
