| Lecturers | Prof. Dr. Sebastian Schöps |
| Type | Lecture |
| Semester | Summer |
| Language | German or English |
| Content | Students understand the theoretical and numerical fundamentals of circuit simulation and how the equations can be derived from Maxwell's equations. Circuit properties can be expressed in tems of graph theory. The sparse systems of equations such as the flux/charge oreinted modified nodal analysis can be assembled. In order to solve the obtained systems, different numerical methods for the simulation of circuits are relevant. This includes methods for the solution of linear systems (direct and iterative solvers), root-finding algorithms for nonlinear systems and implicit time integration methods. Mathematical concepts such as stability, convergence order or complexity are known and can be employed to judge the advantages and disadvantages of the various methods. Eventually, the students are able to programm their own circuit simulator, that can return both frequency as well as time domain solutions of electric networks. |

| Content | The Boundary Element Method (BEM) has developed into an important alternative to domain-oriented approaches (like Finite Elements), ever since fast implementations are available. The BEM reduces the dimensionality of the problem and can easily take into account unbounded domains. Starting from the representation formulas of Kirchhoff and Stratton-Chu boundary integral equations are derived. Next, their discretization by collocation and Galerkin methods is discussed. The resulting fully populated matrices have to be compressed for practical applications, by Fast Multipole or Adaptive Cross Approximation methods. Practical examples for application of the BEM are considered, for instance acoustic and electromagnetic scattering problems, and thermal analysis. Programming homework will be assigned, to deepen the students' understanding of the contents. |

| Content | Students with basic programming experience will get an introduction to computational programming of numerical algorithms in C++. The first half of this course will focus on basics of the programming language C++, and highlight aspects in which the language differs from scripting languages such as Python or Matlab. Subsequently, the focus of the course will be on efficient memory management: We discuss modern best practices such as the usage of reference types and idioms like RAII (“Resource Acquisition is Initialization”) rather than classical pointers (“Raw-Pointers”). During the exercises, we illustrate the effect of memory handling for numerical linear algebra applications, and introduce STL (Standard Template Library) data structures in this context. In the second half of the lecture, the students implement more complex algorithms from different application areas using the “Eigen” library (for linear algebra) and openMP (for parallel computing). Here, the focus lies on understanding both libraries, improving the students' programming level from the first lecture half, and solving programming tasks from different areas such as stochastics, numerical solution of differential equations, and approximations. |

| Content: | In the recent years, the amount of literature that deals with physical models in terms of differential forms (DF) has increased strongly. For instance, DF allow a clear and elegant representation of electromagnetics (EM). The operators grad, curl, and div of vector analysis are replaced by a single operator of the exterior derivative. Similarly, the integral theorems of Gauss and Stokes are replaced by a single integral theorem. Vector analysis is limited to three dimensions, while DF can be applied to any dimensions. This is useful for the relativistic formulations in four dimensions. Since DF can be canonically integrated over appropriate domains they lend themselves naturally to discretizations of the finite integration type. This lecture series provides an introduction into DF calculus, and its relation to vector analysis. Maxwell‘s equations and the constitutive relations are expressed in terms of DF, and the main steps into discretization are outlined briefly |

The “Introduction to CE studies” program is aimed at all CE students in their first semester. The aim is to highlight the framework conditions and requirements of the introductory phase of studies and to introduce students to the specifics of CE studies. Building on this, helpful techniques are provided to enable self-organized and independent study. In terms of content, the program deals with the special situation of CE students in their first semester, who are in transition from school to university and have to face new demands of learning and working at university. These include self-organization, new and unfamiliar examination situations, new ways of communicating content and working effectively in teams. The program consists of seminar sessions with guided group work phases, mentoring with individual advice and an exam simulation. |

| Content | The course is designed to meet the needs of CE students in the Bachelor's degree program and meets the demands placed on CE students during this work-intensive period. As part of the seminars and in teamwork, the basics of scientific work and presentation for engineers are dealt with and systematically developed by the participants in independent work. In addition, the course offers the opportunity to acquire introductory and advanced knowledge in the use of LaTeX. Furthermore, numerical calculations with Python will be discussed and an introduction to computing on a high-performance computer will be given. For further support, help desks are offered in addition to the workshops, where all questions regarding the advanced processing in the examination stages can be clarified in consultation hours with the trainers. The presentation of the results of the scientific term paper concludes the course. |
