Course Description (back to top)


This course is on the finite element methods (FEM) for solving elliptic and time-dependent partial differential equations (PDEs). It covers the mathematical formulation, numerical analysis, and efficient computations of FEM, with applications to continuum mechanics. It also surveys some advanced, research-oriented topics, including shock capturing, high-order and super-convergence, mesh adaptation, multigrid methods, domain decomposition, and hybrid methods. Computing projects will involve programming in Python and MATLAB.

Learning Objectives:

  • Master the fundamentals of the finite element methods
  • Master the mathematical analysis of the finite elements for coercive and non-coercive PDEs
  • Understand the workflow of FEM, including its implementation and pre- and post-processing
  • Understand the computational aspects in linear solvers and domain decomposition
  • Get acquainted with recent developments in FEM, including high-order and hybrid methods

Prerequisites:

  • AMS 510 & AMS 527 or pre-approval by the instructor. In particular, it is a good idea to familiarize yourself with the following concepts: Gaussian elimination; vector calculus; Green's theorem; initial value and boundary value problems; conditioning and stability; interpolation and approximation; finite difference methods; implicit Runge-Kutta methods; Gaussian quadrature
  • AMS 595 or programming experience in Python

Course Delivery Mode and Structure (back to top)


This course primarily uses Zoom (https://it.stonybrook.edu/services/zoom) for lectures and office hours and uses Microsoft Teams (https://it.stonybrook.edu/services/office-365) to facilitate communications between faculty and students, submission of assignments, and posting grades. All links are available through the Blackboard learning management system. All assignments and course interactions will utilize the Internet. See the “Technical Requirements” section for more information. In Teams, you will access online lessons, course materials, and resources.

Course-related questions should be posted in the General channel in Teams. For personal/private issues, my preferred method of contact is private chat messages on Teams or email listed at the top of this syllabus. I strive to respond to your emails as soon as possible, but please allow between 24-48 hours for a reply. All email communication will be sent to your Stony Brook University email account. You must have an active Stony Brook University e-mail account and access to the Internet. Please plan on checking Teams regularly and your SBU email account for course related messages or set up your SBU email account to forward to your personal email account. To log in to Stony Brook Google Mail, go to http://www.stonybrook.edu/mycloud and sign in with your NetID and password.

Important announcements will be sent on Blackboard and Teams. These will be posted in the class and may or may not be sent by email I will participate and post regularly in the discussion board and provide feedback on assignments within a week. Regular communication is essential in online classes. When we are participating in class discussions the expectation is that you will respond regularly to your peers and questions posed to your responses. Logging in regularly, checking the discussion board and participating with your colleagues ensures that you are able to remain an active member of the class.

Grading Policy (back to top)


The course involves five (written & computing) homework assignments, one midterm exam after the first three parts, and a final project with presentation.
  • Home assignments: 25%
  • Midterm exam: 30%
  • Final project: 40% (25% on code and/or report, and 15% on presentation)
  • Class participation: 5% (questions and discussions)
Assignment Policy

Homework assignments are due typically two weeks after they are assigned. You are allowed to discuss course materials and homework problems in small groups, but limited to discussion of general ideas only. You must write your solutions completely independently. Under no circumstances may you copy solutions from any source, including but not limited to other student's solutions, official solutions distributed in past terms, and solutions from courses taught at other universities. Violation of these rules may result in disciplinary actions.

Exam

The midterm exam will be closed-book, but you are allowed to bring a single-sided, one-page, letter-size cheat sheet, which you must prepare by yourself. The exams will be proctored using Zoom/Teams. You are also expected to have access to a private and quiet room during the exam. If your room is too noisy, earplugs or soundless hearing-protection headset can be used during the exam.

Project

Each student will have a mini-research project on one of the more advanced topics. The project can be individual or team-based, and it can be theoretical, computational, or application-oriented. The project will be composed of literature review, theoretical analysis or algorithm development, numerical verification or results, a report, and a presentation. A list of potential topics will be posted on Teams.

Attendance

All students are expected to attend the lectures and the exam synchronously.
