Detailed Description

Interpolation schemes.

The value of each entry is the suffix of the C++ routine toolbox::blockstructured::interpolateHaloLayer_AoS_<suffix>().

PiecewiseConstant copies the coarse value into all fine volumes which it covers.
Linear interpolates linearly along the face. As the coarse face does not hold the coarse volumes beyond its two ends, the scheme extrapolates constantly there. Linear extrapolation would be more accurate, but it can produce unphysical values such as negative densities next to steep gradients (toolbox::blockstructured::internal::createLinearInterpolationMatrix()).
