Bachelor's thesis presentation. Joon is advised by Manish Kumar Mishra and Univ.-Prof. Dr. Hans-Joachim Bungartz.
SCCS Kolloquium
The SCCS Colloquium is a forum giving students, guests, and members of the chair the opportunity to present their research insights, results, and challenges. Do you need ideas for your thesis topic? Do you want to meet your potential supervisor? Do you want to discuss your research with a diverse group of researchers, rehearse your conference talk, or simply cheer for your colleagues? Then this is the right place for you (and you are also welcome to bring your friends along).

Joon Kim: Exploring the Discrete Element Method: Simulation of Granular Particles using AutoPas
SCCS Colloquium |
Granular materials, such as powders and grains, are prevalent in both natural and industrial processes, including those in the pharmaceutical and food-processing sectors. To optimize the processing of such materials, simulation technology based on Discrete Element Method (DEM) is widely employed. DEM uses physics-based contact force and
heat models to simulate interaction between individual particles. In this study, we examine the force and heat models for spherical particles and present an implementation of DEM using the node-level short-range particle simulation library, AutoPas. Furthermore, we show a straightforward implementation of non-spherical DEM by approximating arbitrary particle shapes using subspheres, utilizing md-flexible, a molecular dynamics simulator integrated within AutoPas.
Furthermore, to demonstrate the effectiveness of our approach, we provide simulation results from several scenarios, particularly a rotating square tumbler and a fluidized bed. In the rotating square tumbler, we observe particle heating resulting due to frictional interactions, as well as heat conduction along the tumbler walls. These thermal effects can
either amplify or oppose each other, depending on the thermal settings of the walls. In the fluidized bed, solid particles are initially packed densely. As gas particles exert significant pressure on these solids, they disrupt the alignment of the solid particles, leading to a reduction in pressure and the formation of a fluidized state.
Additionally, we highlight the benefits of AutoPas’s auto-tuning capabilities in improving the efficiency of these simulations. For the rotating tumbler, AutoPas selects the Verlet Cluster Lists algorithm for neighbor identification with the AoS (Array of Structures) particle data layout, which proves more efficient than other variants, such as the Linked Cells algorithm. In the fluidized bed scenario, which involves dynamic changes in particle density, AutoPas adapts by transitioning from Linked Cells with AoS to Linked Cells with
SoA, and eventually to Verlet Cluster Lists with AoS, as the particle density increases.

Contribute a talk
To register and schedule a talk, you should fill the form Colloquium Registration at least four weeks before the earliest preferred date. Keep in mind that we only have limited slots, so please plan your presentation early. In special cases, contact colloquium(at)mailsccs.in.tum.de.
Colloquium sessions are now on-campus. We have booked room MI 02.07.023 for WS24/25. You can either bring your own laptop or send us the slides as a PDF ahead of time. The projector only has an HDMI connection, so please bring your own adapters if necessary.
Do you want to attend but cannot make it in person? We now have a hybrid option. Simply join us through this BBB room: https://bbb.in.tum.de/shu-phv-eyq-rad
We invite students doing their Bachelor's or Master's thesis, as well as IDP, Guided Research, or similar projects at SCCS to give one 20min presentation to discuss their results and potential future work. The time for this is typically after submitting your final text. Check also with your study program regarding any requirements for a final presentation of your project work.
New: In regular times, we will now have slots for presenting early stage projects (talk time 2-10min). This is an optional opportunity for getting additional feedback early and there is no strict timeline.
Apart from students, we also welcome doctoral candidates and guests to present their projects.
During the colloquium, things usually go as follows:
- 10min before the colloquium starts, the speakers setup their equipment with the help of the moderator. The moderator currently is Ana Cukarska. Make sure to be using an easily identifiable name in the online session's waiting room.
- The colloquium starts with an introduction to the agenda and the moderator asks the speaker's advisor/host to put the talk into context.
- Your talk starts. The scheduled time for your talk is normally 20min with additional 5-10min for discussion.
- During the discussion session, the audience can ask questions, which are meant for clarification or for putting the talk into context. The audience can also ask questions in the chat.
- Congratulations! Your talk is over and it's now time to celebrate! Have you already tried the parabolic slides that bring you from the third floor to the Magistrale?
Do you remember a talk that made you feel very happy for attending? Do you also remember a talk that confused you? What made these two experiences different?
Here are a few things to check if you want to improve your presentation:
- What is the main idea that you want people to remember after your presentation? Do you make it crystal-clear? How quickly are you arriving to it?
- Which aspects of your work can you cover in the given time frame, with a reasonable pace and good depth?
- What can you leave out (but maybe have as back-up slides) to not confuse or overwhelm the audience?
- How are you investing the crucial first two minutes of your presentation?
- How much content do you have on your slides? Is all of it important? Will the audience know which part of a slide to look at? Will somebody from the last row be able to read the content? Will somebody with limited experience in your field have time to understand what is going on?
- Are the figures clear? Are you explaining the axes or any other features clearly?
In any case, make sure to start preparing your talk early enough so that you can potentially discuss it, rehearse it, and improve it.
