Solution of the Modified Bratu Problem in SAMRAI

摘要

A model implementation of the solution of an unsteady nonlinear reaction-diffusion on a a SAMR grid using SAMRAI has been developed. This model implementation illustrates the use of new capabilities for implicit timestepping and solution of large-scale systems of nonlinear equations using implementations of inexact Newton methods found in KINSOL and PETSc. This document provides a detailed description of the implementation.
