## Numerical Methods II

Course unit code: FSI-9NM2
Year of study: Not applicable.
Semester: summer
Number of ECTS credits:
 Learning outcomes of the course unit: Many engineering problems make for the solution of differential equation, both ordinary and partial. Skills obtained in this course equip students with the necessary minimum knowledge of basic numerical technics used in today's software packages intended for the solution of differential equations.
 Mode of delivery: Not applicable.
 Prerequisites: Linear algebra, vector calculus, differential and integral calculus, basics of programming.
 Co-requisites: Not applicable.
 Recommended optional programme components: Not applicable.
 Course contents (annotation): The course deals with the numerical solution of differential equations. First initial-value problems are studied (Runge-Kutta methods, linear multistep methods (especially Adams methods and backward differentiation methods), solution of stiff problems). Next solution methods for boundary value problems are introduced (the finite difference method, the control volume method and the finite element methods). The principles of those methods are explained for 1D second order boudary value problem. Main emphasis is placed on the finite element method in two dimensions. The following model problems are studied: elliptic (stationary heat transfer), parabolic (nonstationary heat transfer) and hyperbolic (membrane vibration including eigenproblems).

 Planned learning activities and teaching methods: The course is taught through lectures explaining the basic principles and theory of the discipline.
 Assesment methods and criteria linked to learning outcomes: The exam has an oral part only. The student has to answer one question from the range "numerical solution of initial value problems" and one or two questions from the range "numerical solution of partial diffetential problems" (from which always one concerns the finite element method in 2D). Emphasis is put on understanding the fundamentals of methods, formulae is not necessary to know by heart, it is howewer necessary to understand them and by means of those formulas to explain, how methods work.
 Language of instruction: Czech, English
 Work placements: Not applicable.
 Course curriculum: Not applicable.
 Aims: The aim of the course is to teach students the basic principles of modern computational methods used for the solution of problems described by differential equations. Based on this knowledge they ought to be able to choose suitable software product (exceptionally to write their own program) and then succesfully apply it.
 Specification of controlled education, way of implementation and compensation for absences: Attendance at lectures is facultative, but highly recommended.

Type of course unit:

Lecture: 20 hours, optionally doc. RNDr. Libor Čermák, CSc. The course has 10 two-hours lessons. 1.
