Computer-Supported Solution of Engineering Problems
FEKT-MPPRAcad. year: 2019/2020
An interpretation of the numerical methods implemented in widely-utilized CAD programs is given. This course covers the fundamental methods of solving both linear and nonlinear problems. Within each group, methods are classified according to their features and practical applicability. The comment is then centred on the well proven methods. A comparison is shown of different solutions and methods of calculation and simulation programs in computer labs.
Learning outcomes of the course unit
Students taking the “Computer-supported solution of engineering problems” will understand the solving algorithms of electronic circuits and systems in a wider context in relation to the program for simulation and modelling. Active knowledge of mathematical methods for the numerical solution is a prerequisite for an effective use of professional programs in which these methods are implemented. Students will be able to independently apply computer modelling in different programming environments and control mechanisms for the verification of simulations. Students will have a broader view of the following areas in particular:
- Introduction to computer solutions of electronic circuits
- Methods of analysing linear circuits
- Methods of analysing nonlinear circuits
- Sensitivity analysis of circuits, tolerance analysis
- Computer models of active components of electronic circuits
- Computer models of line
Students should have basic knowledge of mathematics and electrical engineering, which they obtained in obligatory courses their previous study. Completing these courses is not a prerequisite for enrolling on this course.
