Detailed Description

Class HierarchyMathOps provides functionality to perform "composite-grid" mathematical operations on a range of levels in a SAMRAI::hier::PatchHierarchy object.

For nodal destination data, if the provided variable has fineBoundaryRepresentsVariable() == false and synch_dst_cf_interface == true then each routine will call HierarchyMathOps::enforceHangingNodeConstraints() to achieve a conforming bi/trilinear discretization.

Note

All specified variable descriptor indices must refer to SAMRAI::hier::Variable / SAMRAI::hier::VariableContext pairs that have been registered with the SAMRAI::hier::VariableDatabase.
