SAMRAI Documentaion

SAMRAI Overview

Introductory slide presentation.

Reference Manual

Documents the classes in the SAMRAI library.

Documents describing various code functionality in SAMRAI:

• FAC Preconditioner, Robin Boundary conditions - use of FAC solver classes
• Regridding and Richardson Extrapolation - describes how to manage refinement using either a gradient detectionn algorithm or Richardson extrapolation.
• Communication Algorithms and Boundary conditions - describes parallel AMR data communication support and how boundary conditions are invoked.
• Timing and Instrumentation - describes the timing package to assist in performance analysis and to guide the user about which routines are incurring the largest percentage of computation time.
• Vizamrai Writer, VisIt Writer, VisIt Tutorial - describes how to write data that may be postprocessed by the Vizamrai or VisIt tools.
• M4 Macros for Fortran - how to use SAMRAI m4 macros for accessing patch data in fortran
  

Examples using SAMRAI for adaptive problems:

• Laplacian Example - describes three different ways in which one may manipulate data on a SAMRAI patch.
• Poisson - describes how to use the Poisson system solver in SAMRAI
