The package of application programs for the robust multigrid technique: building blocks and diagnostic tools

Abstract

A short description of the application package for the robust multigrid technique is given. The technique unites the processes of construction of multigrid structures, computation of index mappings, evaluation of integrals, usage of multigrid cycles, etc. Since these processes do not depend on problems to be solved, they can be implemented as a unified software. The package allows the users to essentially cut the time required to develop and debug programs for solving a wide range of problems important in practice.
