2. Objectives and learning outcomes

2.1 Objectives

The aim of this course is that students learn and apply at a good skill level the possibilities of numerical solution of engineering problems on computers. The principles of the most relevant numerical techniques including their advantages, disadvantages and applicability are presented during laboratory practices. Students may learn and apply mathematical procedures suitable for solving and visualizing technical problems on computer practices, mainly through examples from civil engineering. A further purpose of this course is to prepare the students for later independent research.

2.2 Learning outcomes

Upon successful completion of this subject, the student:

A. Knowledge

- Has a skill level knowledge of a mathematical environment
- Knows the basic commands of a mathematical environment including procedures, loops, branching, visualization opportunities, text data reading and writing possibilities
- Can distinguish the different computation errors
- Knows methods for solving system of linear equations
- Understands the methods for finding the roots of system of non-linear equations
- Is aware of the difference between the methods of interpolation and regression
- Has a general knowledge of optimization methods
- Is informed regarding various numerical derivation and integration procedures
- Knows several methods for solving initial and boundary value problems in case of ordinary differential equation

B. Skills

- Able to skillfully use a mathematical environment to solve engineering problems
- Able to interpret the upcoming error/warning messages and to fix the specified errors
- Able to knowingly use the software documentation, using which can find the necessary commands, interprets the algorithms and parameters used by the commands
- Able to load text data into a mathematical environment
- Routinely produce charts in a mathematical environment, and modifies them in line with expectations.
- Able to choose the proper algorithm for the specific problem
- Able to fit measurement data with an interpolating or regression curve/surface
- Able to skillfully solve systems of linear or non-linear equations
- Able to solve one or multivariate optimization problems with or without constraints
- Able to differentiate/integrate numerically in case of a certain problem
- Able to transform a higher order differential equation into a system of first order differential equations
- Able to solve ordinary differential equations in case of initial or boundary value problem, even in single and bivariate case

C. Attitudes

- Seeks the most efficient algorithm during the solution
- Susceptible toward the simple and effective program codes
- Attempts to write a well-documented script with comments understandable for others

D. Autonomy and Responsibility

- Independently performs the solution of the problem assigned as homework
- Openly receives the well-founded critical comments, accepts the proposals and integrates them during the further work
- Independently checks in the documentation how to use the commands required to solve the tasks
