public interface Interpolator

This interface defines the interpolate() method which produces a fine grid from the next coarser grid by interpolation.

The Full Multigrid (FMG) algorithm works with grids of different sizes corresponding to different levels. Interpolation is the process of taking a function whose value is known at the grid elements of a grid at a certain level (the coarse grid) and producing the values of the function at the grid elements of a grid at the next finer level (the fine grid). The fine grid and the coarse grid are oriented such that their corner elements coincide.

Method Summary

BoundaryGrid

interpolate(ConstBoundaryGrid grid, SolverResolutionLevels levels) interpolates a function sampled on a specific grid to the next finer grid

Method Detail

interpolate

BoundaryGrid interpolate(ConstBoundaryGrid grid,
                         SolverResolutionLevels levels)

interpolates a function sampled on a specific grid to the next finer grid

.

Parameters:

grid - the input function sampled on a grid at a certain level (size of grid must be 2^level + 1)

levels - the levels

Returns:

the function sampled on a grid at the next finer (higher) level
