Structured adaptive mesh refinement (SAMR) techniques
aim at preserving the high computational performance achievable on uniform
grids on a hierarchically adapted non-uniform mesh. The approach is in
use at all Department of Energy laboratories. The course gives an overview
of the mathematical background, details the employed algorithms, and summarizes
practically relevant applications and their implementation.

Lecture notes (3.3 MB)
Lecture 5 includes a demonstration of the SAMR software AMROC/VTF. Prepare
an own Linux workstation or laptop for this exercise as follows:
1. Set up your system for source code development and scientific visualization.
A short PDF document (bring printout!)
lists the tools to install.
2. Download the installation files for the HDF4 libraries used by AMROC.
A bundled software package (5.4 MB)
including a build script has been prepared to simplify this otherwise
errorprone step.
3. Download the source codes for AMROC/VTF from the download
page. For this exercise, the file AMROC-Clawpack-1.0.tgz (7.8 MB)
is sufficient.
