Overview of numerical methods for the simulation of problems involving solid mechanics and fluid dynamics. The focus is on practical tools needed for simulation, as well as the necessary continuous mathematics involving nonlinear hyperbolic partial differential equations. Possible topics include the finite element method, highly deformable elastic bodies, plasticity, fracture, the level set method, Burgers' equation, compressible and incompressible Navier-Stokes equations, smoke, water and solid-fluid coupling.
Please refer all questions about course material and practices to the CAs before contacting Professor Fedkiw. If you have a question for the CAs, please make sure that it isn't answered on this webpage before contacting them. Also, please do not show up outside of scheduled office hours without first making an appointment. When emailing the CAs, make sure to include "CME306" or "CS205B" somewhere in the subject of your message.
The first chapter of this book is available on the SIAM website, and is on permanent reserve at the Mathematical and Computer Science Library.

In addition to lecture, there will be a section run on Wednesday from 5:30PM to 6:30PM and repeated on Friday from 3:00PM to 4:00PM, which covers tools necessary for the completion of the theory-track homework. While not manditory, it is strongly recommended for any students who intend to take the iCME Qualifying Exams.
| Class | Description |
|---|---|
| Discussion 1 | Convergence, Consistency and Stability, Von Neumann analysis, and the Lax-Richtmyer Equivalence Theorem |
| Discussion 2 | Modified Equations, Dissipation vs. Dispersion, Rigid Body Rotations |
There will be a problem set assigned each week which will be posted on Tuesday at 11:00AM. There are two separate tracks of homework: theory (which involves more qualifying exam preparation), and application (which involves more software development). If you are taking the iCME qualifying exams, you are strongly encouraged to take the theoretical track. If you are looking for the application homework, take a look at CS 205B.
Homework will be graded in coarse, half-point increments between 0 and 2 points.
You may collaborate on homework assignments provided each student writes up his or her own solutions and clearly lists the names of all the students in the group.

Homework must be submitted physically either in class or in the bin outside Gates 204 by 11 AM. Graded homework will be available for pickup in the Gates 377 filing cabinets.
Depending on class performance on homework and exams, there will be a small number of optional extra credit assignments. These assignments will require you to implement some of the numerical schemes discussed during the course. Extra credit projects do not have a set point value; rather, they will be taken into account at the end of the quarter when determining your final letter grade.
Please note that you are free to do, as extra credit, the homework from the applied track.
| Assignment | Due Date |
|---|---|
| Extra Credit 1(tex) | 2008-5-26 |
| Extra Credit 2(tex) | 2008-6-4 |
The final grade will be calculated based on the highest score between your theoretical and applied homework. The lower of the two will be counted towards extra credit. You should complete either all of the theoretical or all of the applied homework, not a mix of the two.
