Detailed Description

template<typename T>
class GridInterpolation< T >

Interpolates a partial solution at every point of a given grid and adds the result multiplied by a given factor to the sparse grid solution.

This accumulator works with different types of grids: those having the dofs in the nodes, containing the boundary nodes or not, and those that with the dofs in the centers of the cells or on the cell edges/sides. The type of the grid is specified by the array of the shifts of the first/last grid points from the boundary: For every dimension there is the value specifying this shift in the units of the grid step. The possible values are in particular 0 for the node-centered grids with the boundary nodes, 0.5 for the cell-centered grids, 1 for the node-centered grids without the boundary nodes.

Note:

The grid types should be specified for the grid of the partial solution and for the grid of the sparse grid solution. These types may be different.
