public void calculate(Field[] coarseFields,
                      Field[] fineFields)

Description copied from class: MultigridOperation

Calculates the multigrid operations on the given set of fields (paired in the array order).

Overrides:

calculate in class MultigridOperation

Parameters:

coarseFields - a list of fields on the coarse grid

fineFields - a list of fields on the fine grid

calculate

protected void calculate(Point finePoint,
                         Point coarsePoint,
                         Field fineField,
                         Field coarseField)

Description copied from class: MultigridOperation

Calculates the operation at the given point for the given field. Typically, one has only to implement this method to implement an operator. The two points given correspond to the same point in space, and will use them to read/write the values on the respective fields.

Specified by:

calculate in class MultigridOperation

Parameters:

finePoint - the point on the fine grid

coarsePoint - the point on the coarse grid

fineField - the field on the fine grid

coarseField - the field on the coarse grid
