+----AT.Ac.univie.imp.loeffler.pde.threeD.fd.InterpolatorByStencil
- public final class InterpolatorByStencil
- extends Object
- implements Interpolator
An interpolator that operates according to an interpolation stencil.
A stencil is a means of defining the relationship of a grid element and its 26 nearest neighbors. In this case the
interpolation stencil defines how to distribute the values of a coarse grid to the values of a fine grid during the
process of interpolation.

TRILINEAR
- the stencil that characterises trilinear interpolation where every element of the fine grid that does not
coincide with an element of the coarse grid is calculated by linear interpolation between its nearest neighbors.
-
InterpolatorByStencil(Stencil)
- construct from interpolation stencil.
-
interpolate(ConstBoundaryGrid)
- implements method from Interpolator.
