Examples include heat transfer, electromagnetic radiation, water flow, and propagation of sound waves.

The three basic types of PDE are elliptic, parabolic and hyperbolic equations.

The goal of the course is that the students learn

Lectures on period 4:

Feb 5, 2009, 9:15-12:00 in hall TC131. Introduction to weak derivatives and Sobolev spaces.

Feb 12, 2009, 9:15-12:00 in hall TC131. Solution of elliptic equations using the variational principle. Finite element method.

**Note:** There is no lecture on week 8 (16.2.-20.2.2009).

After the two initial lectures by professor Siltanen, the students will explain parts of the textbook as a presentation (60 minutes long).

The lectures will be graded, and that grade represents 40% of the final grade of the course.

Here are some instructions for the presentations.

The time for the presentation is 60 minutes including 5 minutes for questions. Try not to speak overtime as that will lower your grade. The talk should contain

The times above are suggestions only.

The structure of the textbook is such that for each PDE type (elliptic, parabolic, hyperbolic) there is a theoretical section

as well as a section for Finite Difference method and for Finite Element Method. It is advisable to follow these in your presentation.

You can use the equipment available in the classroom (computer, projector, and whiteboard).

Here is Exercise 2.

The exercise will be on Friday, February 20, at 12-14 in room SJ202.

Period 5 is devoted to preparing a project work. If you have questions or problems during the preparation of the project work,

please contact the course assistant Juho Linna by email and schedule a meeting with him if necessary.

The idea of the project work is to implement and test one of the numerical solution methods discussed in the course.

You can choose either finite difference or finite element method, and the equation type and dimension is one of the following:

(a) Elliptic equation in dimension 2,

(b) Parabolic equation in dimension 2+time,

(c) Parabolic equation in dimension 1+time,

(d) Hyperbolic equation in dimension 2+time,

(e) Hyperbolic equation in dimension 1+time.

Choose the simplest possible constant coefficient equation and the simplest possible domain (such as rectangle).

Also, it is important to choose such a problem where analytic solution is also available for comparison with the numerical results.

**First deadline April 8, 2009:** return written plan electronically by email to Juho Linna and Samuli Siltanen.

No numerical work is needed at this point; you should just explain what will be computed (choice of equation, method, and domain).

Please include the matrix form of the final computation.

**Final deadline May 8, 2009:** Return the final report introduction, method, and numerical results.

It is important to include a plot of the analytic solution and of the numerically computed solution.

Also, a table is needed where it is shown how refining the computational discretization leads to smaller error in the computation.

The report (in pdf format) and the Matlab codes are returned to the assistant for grading.
