Teaching Advanced Topics in Numerical Engineering Using Project-Based Learning Andreas Apostolatos, Sebastian Gross IEEE Global Engineering Education Conference Educon, 2024 This case study discusses the use of computational platforms and resources for the organization and delivery of lectures in Numerical Engineering using Project-Based Learning (PBL). Additionally, this paper introduces elements of Flipped Classroom. The goal is to demonstrate how modern teaching techniques can enhance the quality of education for students and provide lecturers with an efficient method to set and evaluate Learning Objectives using Bloom's Taxonomy. The evaluation of Learning Outcomes, with a focus on Formative Assessment, is herein extensively discussed. The methods and results presented herein are based on the preparation and delivery of the master-level courses Advanced Finite Element Methods (AFEM) and Advanced Finite Element Methods Lab (AFEM-Lab) that took place in Summer Semester 2023 and Winter Semester 2023–24, respectively, at the Technical University of Munich (TUM). The results presented herein clearly show the effectiveness of using computational platforms and formative assessment both for PBL and Flipped Classroom in the context of advanced academic teaching.
Exploring the Synergy of Simulation and Hardware in Project-Based Learning Lam Aun Cheah, Andreas Apostolatos 2024 IEEE 3rd German Education Conference Gecon 2024, 2024 Project-based learning (PBL) has emerged as a transformative pedagogical approach that promotes deep learning, constructivist principles, and student engagement by immersing learners in authentic, real-world challenges. However, existing PBL methods often face difficulties in providing genuinely realistic experiences and access to the necessary resources. The present study explores the integration of simulation tools and hardware platforms within a PBL environment focused on mobile robotics, with the aim of addressing these challenges and enhancing the overall learning experience. Specifically, we investigated the synergistic combination of MATLAB®/Simulink® simulations and the Zumo mobile robot hardware in a first-year general engineering course. Through a blended learning approach that combined online materials with in-class activities, students programmed and simulated robot behavior virtually, performed hardware-in-the-loop validation, and participated in a line-following robot competition as a competition-driven assessment. To evaluate the effectiveness of this teaching format, quantitative and qualitative data were collected through surveys, observations, project assessments, competition performance, and interviews. The results demonstrate significant improvements in student learning outcomes, including knowledge acquisition, critical thinking and problem-solving abilities, and the practical application of theoretical concepts.

Teaching the Finite Element Method with Notebooks and Autograded Exercises Andreas Apostolatos, Sebastian Gross, Kai-Uwe Bletzinger 2022 IEEE German Education Conference Gecon 2022, 2022 In this study we present the methods applied for the transformation of the lecture "Advanced Finite Element Methods" offered by the Chair of Structural Analysis at the Technical University of Munich to a flipped classroom format. This format uses interactive notebooks to illustrate course content, autograded exercises to reiterate the learnings, a hybrid lecture setup combining both in-person and virtual lectures to allow for a maximum of student flexibility, shared drive folders for distributing material with the course participants, and online computational platforms to avoid the hurdle of software availability and compatibility. To evaluate this lecture format, a survey was sent to the participants. The student performance as well as survey results show that this innovative way of teaching significantly enhances the learning experience and the learning outcome while meeting the participants' expectations.
An isogeometric b-rep mortar-based mapping method for non-matching grids in fluid-structure interaction Andreas Apostolatos, Altuğ Emiroğlu, Shahrokh Shayegan, Fabien Péan, Kai-Uwe Bletzinger, Roland Wüchner Advanced Modeling and Simulation in Engineering Sciences, 2021 In this study the isogeometric B-Rep mortar-based mapping method for geometry models stemming directly fromComputer-Aided Design(CAD) is systematically augmented and applied to partitionedFluid-Structure Interaction(FSI) simulations. Thus, the newly proposed methodology is applied to geometries described by theirBoundary Representation(B-Rep) in terms of trimmed multipatchNon-Uniform Rational B-Spline(NURBS) discretizations as standard in modern CAD. The proposed isogeometric B-Rep mortar-based mapping method is herein extended for the transformation of fields between a B-Rep model and a low order discrete surface representation of the geometry which typically results when theFinite Volume Method(FVM) or theFinite Element Method(FEM) are employed. This enables the transformation of such fields as tractions and displacements along the FSI interface whenIsogeometric B-Rep Analysis(IBRA) is used for the structural discretization and the FVM is used for the fluid discretization. The latter allows for diverse discretization schemes between the structural and the fluidBoundary Value Problem(BVP), taking into consideration the special properties of each BVP separately while the constraints along the FSI interface are satisfied in an iterative manner within partitioned FSI. The proposed methodology can be exploited in FSI problems with an IBRA structural discretization or to FSI problems with a standard FEM structural discretization in the frame of theExact Coupling Layer(ECL) where the interface fields are smoothed using the underlying B-Rep parametrization, thus taking advantage of the smoothness that the NURBS basis functions offer. All new developments are systematically investigated and demonstrated by FSI problems with lightweight structures whereby the underlying geometric parametrizations are directly taken from real-world CAD models, thus extending IBRA into coupled problems of the FSI type.
Systematic evaluation of the interface description for fluid–structure interaction simulations using the isogeometric mortar-based mapping Andreas Apostolatos, Guillaume De Nayer, Kai-Uwe Bletzinger, Michael Breuer, Roland Wüchner Journal of Fluids and Structures, 2019 Within this study the influence of the interface description for partitioned Fluid–Structure Interaction (FSI) simulations is systematically evaluated. In particular, a Non-Uniform Rational B-Spline (NURBS)-based isogeometric mortar method is elaborated which enables the transfer of fields defined on low-order and isogeometric representations of the interface along which the FSI constraints are defined. Moreover, the concept of the Exact Coupling Layer (ECL) using the proposed isogeometric mortar-based mapping method is presented. It allows for smoothing fields that are transferred between two standard low-order surface discretizations applying the exact interface description in terms of NURBS. This is especially important for highly turbulent flows, where the artificial roughness of the low-order faceted FSI interfaces results in spurious flow fields leading to inaccurate FSI solutions. The approach proposed is subsequently compared to the standard mortar-based mapping method for transferring fields between two low-order surface representations (finite volume method for the fluid and finite element method for the structure) and validated on a simple lid-driven cavity FSI benchmark. Then, the physically motivated 3D example of the turbulent flow around a membranous hemisphere (Wood et al., 2016) is considered. Its behavior is predicted by combining the large-eddy simulation technique with the isogeometric analysis to demonstrate the usefulness of the isogeometric mortar-based mapping method for real-world FSI applications. Additionally, the test case of a bluff body significantly deformed in an eigenmode shape of the aforementioned hemisphere is used. For this purpose, both “standard” low-order finite element discretizations and a smooth IGA-based description of the structural surface are considered. This deformation is transferred to the fluid FSI interface and the influence of the interface description on the fluid flow is analyzed. Finally, the computational costs related to the presented methodology are evaluated. The results suggest that the proposed methodology can effectively improve the overall FSI behavior with minimal effort by considering the exact geometry description based on the Computer-Aided Design (CAD) model of the FSI interface.
