walberla::field::TrilinearFieldInterpolator< Field_T, FlagField_T > Class Template Reference

Detailed Description

template<typename Field_T, typename FlagField_T>
class walberla::field::TrilinearFieldInterpolator< Field_T, FlagField_T >

Interpolator for walberla::field::GhostLayerField with trilinear strategy.

This interpolator uses trilinear interpolation to obtain the interpolated value from the interpolation position. If at least one of the cells, that are required for trilinear interpolation, i.e. the 8 closest cells, is not contained in the evaluation mask, the nearest-neighbor interpolation (see NearestNeighborFieldInterpolator.h) will be used instead. Never construct this interpolator directly, but use the functionality from FieldInterpolatorCreators.h instead.
