Performs the interpolation between the primal and dual grids via a stencil approach. For performance reasons, for each field we store the entirety of the y dimension and the number of x slices required by the stencil. Therefore a new interpolation is simply the calculation of one point and reuse of existing computed points (unless this is the first x or y.) The applicable interpolation stenciled data is copied out, with :,1,1 being the central point, minus and plus in each y and x dimension as determined by the stencil size. This is done so that the stencil size can easily be different for each flow field and this is the case with u (where we need u-2 in the X.) More...

subroutine | calculate_interpolated_cell_value (local_grid, j, i, interpolate_in_dimension, field, column_stencil_values) |
Calculates the interpolated values for each point in a column. The exact method of interpolation depends on whether we are interpolating in the w, y or x dimension. More... | |
