Tutorial: Deal. II Finite Element Library
Guido Kanschat, Texas A&M University
October 11 and 13, 2010, 2 p.m.-5 p.m., Lind Hall 305

Abstract: In the first part I will introduce deal.II and discuss its capabilities and limitation. I will give an overview of the development paradigms of the library and present the structure of a typical application based on it in order to address the question whether deal.II is the right tool for your purposes or not.

The second part of the tutorial focuses on the implementation of basic model problems, following the first six steps of the online tutorial. Starting with generating and refining simple meshes (step 1), we move on to solving Poisson's equation (step 3). We modify the program to study how to use different finite elements, solvers and to implement other bilinear forms. We wrap up by introducing techniques for dimension independent programming, adaptive iterations and multilevel methods.

The tutorial closes with the discussion of more advanced applications. We study the handling of systems of equations at hand of the Lame-Navier equations of elasticity, the (linear) Darcy equations for porous media flow, and the Stokes equations. Participants are welcome to suggest additional applications (possibly in advance). The tutorial is open-ended and we can continue working on projects during the next months.

Clawpack Tutorial
Randall J. LeVeque, University of Washington
October 4-6, 2010, 2-3 p.m., Lind Hall 305

Clawpack (Conservation Laws Package) is an open source software package for solving hyperbolic systems of partial differential equations in one or more space dimensions, both with and without source terms. Equations of this type appear in a wide variety of wave propagation problems arising in nearly all fields of science and engineering. Applications include acoustics in the atmosphere or ocean, elastic waves such as seismic waves in the earth or ultrasound waves in biological materials, shock waves in aerodynamics or astrophysics, tsunamis and storm surge, detonation waves, traffic jams, and electromagnetic waves such as light pulses.

High resolution shock-capturing finite volume methods are implemented in Clawpack on logically rectangular grids (Cartesian or mapped grids). Adaptive mesh refinement capabilities are included. The core routines are in Fortran and the user interface and graphics capabilities have recently been converted to Python. A number of sample applications are included with the code.

This tutorial will be a hands-on demonstration of how to install the package, try out the sample applications, and set up a new problem, with some discussion of the plotting routines and use of adaptive refinement.

Working seminar: Probabilistic methods in bioinformatics
Thursdays at 2 pm, February 28, 2008
IMA conference room, Lind Hall Room 409
Organizer: Christopher J. Lee, Department of Chemistry & Biochemistry, UCLA (Visiting Faculty at IMA)

Purpose: to discuss challenges arising from the analysis of massive datasets such as high-throughput genomics or proteomics data, and probabilistic methods for analyzing them. Chris will provide some useful introduction to various topics in each session, but leave the time open for informal discussion. Initial discussion: Introduction to the challenges of high-throughput data analysis in "post-genomic" biology, and methods of statistical inference used to solve these problems.
