This course will introduce students to the fundamental structural and fatigue behaviour of steel structures, numerical solution procedures and modelling details. The course aims to achieve a basic understanding of applied mechanics approaches to modelling member behaviour in steel structure problems. The course is addressed to young engineers, who will face the necessity of numerical analysis and applied mechanics more often in their design practice. The purpose of this course is to bridge the gap between applied mechanics and structural steel design using state-of-the-art tools. The students shall become familiar with computer-oriented analyses and assessment methods by using the example of steel constructions. The course will also convey to students the ability to use numerical tools and software packages for the solution of practical problems in engineering.
Content: This course is introductory – by no means does it claim completeness in such dynamically developing fields as numerical analysis of slender steel structures and structural durability. The course intends to achieve a basic understanding of applied mechanics approaches to slender steel structure modelling and structural durability, which can serve as a foundation for the exploration of more advanced theories and analyses of different kind of structures.

Learning goals / competences:
The main goal of this course is to qualify students to numerically solve linear engineering problems by providing a sound methodological basis of the finite element method. In addition to numerical analysis of trusses, beams and plates, the spectrum of possible applications includes analyses of transport processes such as heat conduction and pollutant transport. In seminar papers the students shall apply the basics of the Linear Finite Element Methods learnt in the lectures and solve structural-mechanical problems by means of hand calculations. Furthermore the students are required to program and validate problems in structural analysis and transport processes.
Content:
Introduction to the finite element method in the framework of linear elastodynamics. Based upon the weak form of the boundary value problem principles of spatial discretization using the finite element method are explained step by step. First, one-dimensional isoparametric p-truss elements are used to explain the fundamentals of the finite element method. Afterwards the same methodology is used to develop two- (plane stress and plane strain) and three-dimensional isoparametric p-finite elements for linear structural mechanics. In addition to analyses related to structural mechanics, the application of the finite element method to the spatial discretization of problems associated with transport processes within structures (e.g. heat conduction, pollutant transport, moisture transport, coupled problems) is demonstrated. The second part of the lecture is concerned with finite element models for beams and plates. In this context aspects of element locking and possible remedies are discussed. The lectures are supplemented by exercises to promote the understanding of the underlying theory and to demonstrate the application of the finite element method for the solution of selected examples. Furthermore, practical applications of the finite element method are demonstrated by means of a commercial finite element program.

The energy conservation law for conservative systems and the energy dissipation law for dissipative systems are studied. Various exact and approximate methods for solving dynamical problems, along with the Laplace transform method, the method of normal mode for coupled systems, and the Rayleigh method are developed for free and forced vibrations. Various practical examples and applications to resonance and active vibration control are shown. Further, an overall insight of the modelling and control of active structures is given within the course. The terms and definitions as well as potential fields of application are introduced. For the purpose of the controller design for active structural control, the basics of the control theory are introduced: development of linear time invariant models, representation of linear differential equations systems in the state-space form, controllability, observability and stability conditions of control systems. The parallel description of the modelling methods in structural mechanics enables the students to understand the application of control approaches. For actuation/sensing purposes multifunctional active materials (piezo ceramics) are introduced as well as the basics of the numerical model development for structures with active materials. Control methods include time-continuous and discrete-time controllers in the state space for multiple-input multiple-output systems, as well as methods of the classical control theory for single-input single output systems. Differences and analogies between continuous and discrete time control systems are specified and highlighted on the basis of a pole placement method. Closed-loop controller design for active structures is explained. Different application examples and problem solutions show the feasibility and importance of the control methods for structural development. Within this course the students learn computer aided controller design and simulation using Matlab/Simulink software.

Learning goals / competences:
The main goal of this course is to qualify students to numerically solve nonlinear problems in engineering sciences by providing the methodological basis of the geometrically and physically nonlinear finite element method. In seminar papers the students shall apply the basics of the Advanced Finite Element Methods and solve nonlinear structural-mechanical problems by means of hand calculations. Furthermore the students are required to program and validate problems in geometrically and physically nonlinear structural analysis.
Contents:
Based upon a brief summary of non-linear continuum mechanics the weak form of non-linear elastodynamics, its consistent linearization and its finite element discretization are discussed and, in a first step, specialized to one-dimensional spatial truss elements to understand the principles of the formulation of geometrically nonlinear finite elements. In addition, an overview of nonlinear constitutive models including elasto-plastic and damage models is given. The second part of the lecture focuses on algorithms to solve the resulting non-linear equilibrium equations by load- and arc-length controlled Newton-type iteration schemes. Finally, the non-linear finite element method is used for the non-linear stability analysis of structures. The lectures are supplemented by exercises to support the understanding of the underlying theory and to demonstrate the application of the non-linear finite element method for the solution of selected examples. Furthermore, practical applications of the non-linear finite element method are demonstrated by means of a commercial finite element program.

Acquiring knowledge in fundamentals of the finite element method in the modelling, design and control for geotechnical structures and tunneling problems. The course provides effective methodologies to generate proper models to predict soil-structure interactions by performing nonlinear analysis.
Content: Numerical Simulation in Geotechnics The course gives an overall insight to the numerical simulation of geotechnical and tunneling problems by using the finite element method including constructional details, staged excavation processes and support measures. This encompasses material modeling, discretization in space and time and the evaluation of numerical results. The terms and expressions for creating proper numerical models showing appropriate mesh shapes, boundary and initial conditions are introduced. Different constitutive models with their parameters and potential fields of application for different materials are presented in order to show how accurate results can be obtained. To control the reliability of numerical models, the basics of constitutive parameter calibration, model validation and verification techniques are explained. In connection with the possibilities of 2D and 3D discretization, the basics of invariant model development are explained. To achieve a better understanding of the soil-water interactions in drained, undrained and consolidation analyses, fully coupled hydromechanical finite element solutions are described. Basics of local and global sensitivity analyses are introduced to address the effectiveness of the contributing constitutive parameters as well as constructional aspects within the sub-systems. To perform global sensitivity analyses, which usually requires a vast number of test runs, the meta modeling technique as a method for surrogate model generation is presented. All these methods are consequently applied in the context of a reference case study on a tunneling-related topic. Numerical Simulation in Tunneling This tutorial provides an overview of the most important aspects of realistic numerical simulations of tunnel excavation using the Finite Element Method including staged excavation processes and support measures. This encompasses material modeling, discretization in space and time and the evaluation of numerical results. In the framework of the exercises nonlinear numerical analyses in tunneling will be performed by the participants in autonomous teamwork in the computer lab.

Learning goals / competences:
The main goal of the seminar is to enable students to implement the theories and methods taught in ‘Finite Element Methods in Linear Structural Mechanics’ in an object-oriented finite element program for the analysis of engineering structures.
Content:
The seminar links the theory of finite element methods with object-oriented programming in the sense that the finite element theory is applied within a finite element program developed by the students. In order to gain insights into both topics – object-oriented programming and finite element theory – students implement an object-oriented finite element program for the analysis of spatial truss structures. This combination of the theory of numerical methods with object-oriented programming provides an inspiring basis for the successful study of computational engineering. In the lecture, the fundamentals of the finite element method and object-oriented programming are briefly summarized. The programming part of the course comprises two parts. In the first part, the topic is fixed: Students individually develop an object-oriented finite element program for the linear analysis of spatial truss structures. The program is verified by means of the static analysis of a representative benchmark and afterwards applied for the numerical analysis of an individually designed spatial truss structure. In the second part, students can choose between different options. Either, the application developed in the first part is extended to more challenging problems (nonlinear analysis, other element types, etc.) or students switch to an existing object-oriented finite element package (e.g. Kratos) and develop an extension of that software.

Learning goals / competences:
The students acquire advanced skills of CFD methods for the computation of wind engineering problems such as mean wind parameters and turbulence characteristics for the
assessment of local wind climates (incl. wind farm locations), wind pressures at surfaces for the determination of wind loads
at structures, and gaseous transport in the atmospheric boundary layer for the
prediction of the dispersion of exhausts and particles The students shall be enabled to assess the available numerical tools and to solve the relevant technical problems by choosing the appropriate CFD method.
Content:
This course introduces the details and guidelines for the application of CFD methods in the field of wind engineering. Relevant problems for practical applications and solution procedures are investigated. The theoretical background is taught in the obligatory Fluid Dynamics course while this course aims at the practical application of CFD methods on various wind engineering problems. In general, the steady state RANS approach and the time dependent LES approach are used. The lectures and exercises include all necessary steps of a CFD simulation ranging from the creation of the geometry of the problem to the assessment and presentation of the results. During the semester the commercial software package ANSYS CFX and the open source software OpenFOAM are used. The following working steps are explained and carried out:
Generation of simple geometries and block structured grids and analysis of the influence of the quality of the mesh on the results of the simulation.
Generation of complex geometries and unstructured numerical grids.
Setting up simulations (Pre-Processing): - ◦ Choosing the right boundary conditions. ◦ Choosing the correct turbulence models. ◦ Deciding on the parameters of the finite volume method
such as interpolation schemes for the convective term of the Navier-Stokes equation.
◦ Adding source terms of exhaust for the investigation of pollution in the atmosphere.
Application of the numerical solvers including parallel processing.
Post processing of the most important characteristics of wind engineering flows and presenting them in an adequate manner: ◦ Analysis of mean velocity vector fields around structures. ◦ Analysis of mean and time dependent pressure
distributions on the surface of structures that are exposed to wind to estimate the load due to wind.
◦ Analysis of the aerodynamic forces of lift and drag.

Learning goals / competences:
Project work allows students to work on a problem individually or in small groups. Project groups organize and Coordinate the assignment of tasks independently, while the lecturers take the role of both an advisor and supervisor of the respective project. Further, they check the students’ results at regular intervals. After completion of the project, the students should present their results before the class. The necessity of such a presentation should, however, be agreed upon with the respective supervisor. Project work serves to qualify students to structure Computational Engineering problems, to solving them in teams, and to illustrate the results in the form of a report and a presentation. After completion of the project, the students should have gathered new information and insights into the activities of practicing engineers while acquiring skills in innovative research fields. In the end, the students will be able to present technical projects, and to develop problem solution strategies and will hence also obtain worthwhile communication skills.
Contents:
The project topic is usually determined by the respective lecturer or one of his/her assistants. In addition to this, students may also conduct project work on topics defined by companies from industry or official authorities. However, the project work must be completed under the supervision of one of the course’s lecturers. The projects are usually devised so as to integrate interdisciplinary aspects such as
o Noticing problems and describing them o Formulating envisaged goals o Team-oriented problem solutions o Organizing and optimizing one's time and work plan o Interdisciplinary problem solutions o Literature research and evaluation as well as the consultation
of experts o Documentation, illustration and presentation of results
Literature: The relevant literature will be announced along with the project topic.

Content:
The lecture deals with the parallelization on cluster computers. Distributed-memory programming concepts (MPI) are introduced and best-practice implementation is presented based on applications from scientific computing including the finite element method and machine learning.
Special attention is paid to scalable solvers for systems of equations on distributed-memory systems, focusing on iterative schemes such as simple splitting methods (Richardson, Jacobi, Gauß-Seidel, SOR), Krylov-methods (Gradient descent, CG, BiCGStab) and, in particular, the multigrid method. The mathematical foundations for iterative solvers are reviewed, suitable object-oriented interface structures are developed and an implementation of these solvers for modern parallel computer architectures is developed.
Numerical experiments and self-developed software implementations are used to discuss and illustrate the theoretical results.

Learning goals / competences:
The learning goals of this German language course fulfill the special requirements of foreign students majoring in a subject that uses English as a teaching language. The main focus of the course lies on action oriented speaking, listening, reading and writing comprehension so that the students manage more easily to cope with everyday situations of their life in Germany. With this course students reach a minimum level of all four skills (speaking, listening, reading and writing) in familiar universal contexts or shared knowledge situations such as greeting, small talk, shopping, making appointments, eating out, orientation, biography, healthcare etc. The classes consist of small groups, ensuring that students have ample opportunity to speak as well as having their individual needs attended to. All of our instructors are university graduates experienced in teaching DaF (Deutsch als Fremdsprache - German as a foreign language) and have been selected for their experience in working with students and their ability to make language learning an active and rewarding process. An optional intensive block course after the winter semester helps to activate and to intensify the newly acquired language skills.

Learning goals / competences:
Project work allows students to work on a problem individually or in small groups. Project groups organize and Coordinate the assignment of tasks independently, while the lecturers take the role of both an advisor and supervisor of the respective project. Further, they check the students’ results at regular intervals. After completion of the project, the students should present their results before the class. The necessity of such a presentation should, however, be agreed upon with the respective supervisor. Project work serves to qualify students to structure Computational Engineering problems, to solving them in teams, and to illustrate the results in the form of a report and a presentation. After completion of the project, the students should have gathered new information and insights into the activities of practicing engineers while acquiring skills in innovative research fields. In the end, the students will be able to present technical projects, and to develop problem solution strategies and will hence also obtain worthwhile communication skills.
Contents:
The project topic is usually determined by the respective lecturer or one of his/her assistants. In addition to this, students may also conduct project work on topics defined by companies from industry or official authorities. However, the project work must be completed under the supervision of one of the course’s lecturers. The projects are usually devised so as to integrate interdisciplinary aspects such as
o Noticing problems and describing them o Formulating envisaged goals o Team-oriented problem solutions o Organizing and optimizing one's time and work plan o Interdisciplinary problem solutions o Literature research and evaluation as well as the consultation
of experts o Documentation, illustration and presentation of results
Literature: The relevant literature will be announced along with the project topic.

Content:
The lecture provides an overall insight into the modelling and simulation of incompressible turbulent flows within current commercial software tools. The Reynolds averaged equations of incompressible fluid dynamics are discussed together with the most common turbulence models used for closure, with emphasis on the physical assumptions applied in the derivations. Then the numerical solution of these equations with the Finite Volume method is recapitulated. Different meshing approaches and approximation schemes are discussed with focus on unstructured grids and so called high resolution schemes as applied in the flow solver Ansys Fluent. The choice of suitable boundary conditions for different application fields is presented too. In the computer exercises the students will learn to create meshes with Ansys ICEMCFD with focus on unstructured meshes. Flow simulations will be performed with Ansys Fluent. Emphasis is put on the influence of different numerical approximations on the computed flow physics.

Learning goals / competences:
With the completion of their master thesis, students acquire the ability to plan, organize, develop, operate and present complex problems in Computational Engineering. The master thesis qualifies students to work independently in a Computational Engineering subject under the supervision of an advisor. The associated presentation serves to promote the students’ ability to deal with subject-specific problems and to present them in an appropriate and comprehensible manner. Further, it serves to prove whether the students have acquired the profound specialised knowledge, which is required to take the step from their studies to professional life, whether they have developed the ability to deal with problems from their in-depth subject by applying scientific methods, and to apply their scientific knowledge.
Contents: The master thesis can either be theoretically, practically, constructively or organisationally-oriented. Its topic is determined by the respective supervisor. The results should both be visualised and illustrated in writing in a detailed manner. This particularly includes a summary, an outline and a list of the references used within a specific thesis and obligatory, an oral presentation.
