Abstract

The course introduces students to atomic-level computational methods commonly used in Materials Science, Physics, Chemistry, and Mechanical Engineering. The molecular dynamics and Monte Carlo methods are discussed in depth, from the introduction to the basic concepts to the overview of the current state-of-the-art. Some of the emerging methods for mesoscopic and multiscale modeling are also discussed in the context of real materials-related problems (mechanical and thermodynamic properties, phase transformations, microstructure evolution during processing). Success stories and limitations of contemporary computational methods are considered.

The emphasis of the course is on getting practical experience in designing and performing computer simulations. Pre-written codes implementing atomistic computational methods will be provided. Students will use and modify the pre-written codes and write their own simulation and data analysis codes while working on their homework assignments and term projects. A set of example problems for term project will be provided, although students are encouraged to choose a project relevant to their thesis research.

Recent research articles in the area of atomistic modeling will be discussed, with each student leadong a discussion of a recent research paper. Students will learn to assess the quality and significance of published computational results.

Syllabus


Topics that will be covered include:


Term project

Objective: To get experience in designing and performing computer simulations.

Parts of the project:

  1. Design (or adapt an idea from literature) a simulation that is of scientific or computational interest to you
  2. Choose and justify a computational approach appropriate for the problem of interest
  3. Write the code (or parts of the code that have not been supplied)
  4. Run simulations and analyze the results
  5. Prepare a report; include electronic copies of your code
  6. Present your results to the class (mini-symposium)
Timeline:
February 4th - have project approved by instructor
March 3rd - turn in introduction and discuss progress with instructor (optional)
May 8th - turn in research paper; give a presentation to the class at a mini-symposium

Tentative program of the mini-symposium can be found here

A set of example problems for term projects can be found here.

Projects: A problem chosen for the term project should have some science content and be doable in the timeframe of one semester. Students are encouraged to choose a project relevant to their thesis research. If the intention is to continue computational work in the future, the term project may be a well-defined part of a larger research project.


Discussion of published research articles

Each student will lead a discussion of a recent research paper in the area of atomistic simulations (~10-15 min). Papers will be posted at least one week before the discussion.
