2017: Fundamentals of Simulation Methods

25.07.2017

Winter semester 2017/2018

by Frauke Gräter and Rüdiger Pakmor

This lecture (MVComp1) is part of the specialization in Computational Physics within the physics masters degree at Heidelberg University. The objectives of this course are to endow students with the capacity to identify and classify common numerical problems, to reach an active understanding of applicable numerical methods and algorithms, to solve basic physical problems with adequate numerical techniques, and to recognize the range of validity of numerical solutions.

TOPICS

  • Basic concepts of numerical simulations, continuous and discrete simulations
  • Discretization of ordinary differential equations, integration schemes of different order
  • N-body problems, molecular dynamics, collisionless systems
  • Discretization of partial differential equations
  • Finite element and finite volume methods
  • Lattice methods
  • Adaptive mesh refinement and multi-grid methods
  • Matrix solvers and FFT methods
  • Monte Carlo methods, Markov chains, applications in statistical physics

Examples will include molecular and astrophysics problems.

ORGANIZATION

The lecture takes place weekly, Tuesdays and Thursdays, 9:30-11:00, in INF 227 / SR 1.403/1.404

Exercises will take place on Fridays, in INF 205 / PC-Pool SW 2

Prior knowledge in a programming language and experience with plotting software is highly recommended for the course. There will be a short written examination at the end, and active and successful participation in the homework/exercises is a prerequisite for participation in the final exam and obtaining the credit points for the lecture. The use of Moodle is foreseen for the lecture. Those of you who wish to acquire the credit points should please register to the Moodle (password will be announced at the first lecture).

Access to the script and exercises are provided through Moodle.

Über das HITS

Das HITS (Heidelberger Institut für Theoretische Studien) wurde 2010 von dem Physiker und SAP-Mitbegründer Klaus Tschira (1940-2015) und der Klaus Tschira Stiftung als privates, gemeinnütziges Forschungsinstitut gegründet. Es betreibt Grundlagenforschung in den Naturwissenschaften, der Mathematik und der Informatik. Zu den Hauptforschungsrichtungen zählen komplexe Simulationen auf verschiedenen Skalen, Datenwissenschaft und -analyse sowie die Entwicklung rechnergestützter Tools für die Forschung. Die Anwendungsfelder reichen von der Molekularbiologie bis zur Astrophysik. Ein wesentliches Merkmal des Instituts ist die Interdisziplinarität, die in zahlreichen gruppen- und disziplinübergreifenden Projekten umgesetzt wird. Die Grundfinanzierung des HITS wird von der Klaus Tschira Stiftung bereitgestellt.
