Synopsis:

After elementary tools of linear algebra (matrix, determinant, Gaussian elimination) are recalled, iterative methods for solving systems of linear algebraic equations are in the focus. Then, the finite difference method and the finite element method are presented and their applications to problems based on differential equations are shown. Attention is also paid to basic methods for solving initial value problems in ordinary differential equations.

Requirements:

Elements of calculus (diffrentiation, integration) are assumed. Elementary knowledge of matrix and vector algebra is appreciated, nevertheless, all necessary tools will be reviewed.

At least 70% excercise class attendance.

Syllabus of lectures:

1. Matrix, inner product of vectors, eigenvalues and eigenvectors of a matrix, spectrum of a matrix.

2. Normed linear space, matrix and vector norms, condition number.

3. Iterative methods for solving systems of linear algebraic equations, sparse matrices.

4. One-step methods for solving initial value problems for ordinary differential equations.

5. Function spaces, inner product of functions, differential operators.

6. Variational principle in 1D problems with positive definite operators, functional of energy, generalized (weak) solution.

7. Approximate solution obtained by variational methods (Ritz method and the finite element method in 1D).

8. Poisson equation in 2D, boundary conditions, applications, Ritz method, finite element method.

9. The finite difference method for 1D boundary value problems and eigenvalue/eigenfuncion problems. Various boundary conditions.

10. Finite difference method for 2D elliptic boundary value problems.

11.Wave equation, numerical solution by the finite difference method, stable and unstable method.

12. Transient heat equation, numerical solution by the finite difference method (in 2D - just for information), stable and unstable method.

13. Reserve

Syllabus of tutorials:

Exercise classes follow the topics of lectures.

Study Objective:
