Best Papers and Posters from the COMSOL Conference 2023 Munich

November 30, 2023

The COMSOL Conference 2023 returned in person this year in Munich, Germany, where the multiphysics simulation community formed new connections, learned about the latest advancements in the COMSOL Multiphysics® software, and drew inspiration from each other’s innovative work. During the three-day event, engineers, researchers, and scientists across industries showcased their findings through poster and slideshow presentations. Six teams earned special recognition for their work, receiving Best Paper and Best Poster awards.

200+ Presentations Showcasing a Wide Range of Simulation Use Cases

The 150 posters and 50+ papers featured at the COMSOL Conference 2023 Munich covered a wide range of topics, including heat transfer and phase change; batteries, fuel cells, and electrochemical processes; bioscience and bioengineering; renewable energies; and much more. The dedicated conference program committee consisting of 48 members from different industries and research institutions carefully reviewed and evaluated the abstracts that were submitted and decided which ones to approve. They also selected the three top papers to win the Best Paper awards. We are grateful for the program committee members’ diligent efforts!

During the live event, presenters showcased their posters and discussed their work in detail, leading to in-depth discussions and feedback. After looking through the poster hall, conference attendees voted for their favorite posters to crown the three Best Poster award winners. Those who submitted full-length papers will continue to receive recognition long after the event through the Technical Papers and Presentations gallery, which is now live.

Without any further ado, let’s see who took home awards for their work at the COMSOL Conference 2023 Munich.

Top 3 Papers

Electrochemical Deposition for PCB Applications

The first of the Best Paper award winners were Sascha Loebel of Chemnitz University of Technology and fellow researchers S. Braun of Fraunhofer ENAS; M. Becker of NB Technologies Gmbh; and P. Steinert and A. Schubert, both of the Chemnitz University of Technology, for their paper titled “Modeling Electrochemical Deposition of Aluminum from Ionic Liquids for PCB Applications”.

In the paper, they showcase how they modeled the electrochemical deposition of aluminum from an ionic liquid electrolyte on a PCB substrate. In the first part of their two-stage modeling approach, fluid dynamics within a process chamber were characterized using a macroscale model based on CAD data. In the second stage, the results from the first model were implemented in a microscale model for calculating electrolyte flow and ion transport in the vicinity of a vertical interconnect access (via) that needed coating. By linking these two models, they were able to consider the fluid dynamic conditions within a process chamber and compare their results to similar experimental investigations.

Measuring Energy Efficiency of Quay Walls

The development of energy geostructures is an innovative way to help reduce our reliance on fossil fuels. These structures can supply mechanical support to overlying structures and/or soil as well as geothermal energy for space heating and cooling. Despite their promising features, the thermal and thermomechanical behavior of geostructures is not well understood.

As a way to gain more understanding, Marco Gerola of the University of Milan, F. Cecinato of the University of Milan, J.K. Hassnoot of CRUX Engineering BV, and P.J. Vardon of Delft University of Technology turned to multiphysics modeling. This team developed models that helped them gain an in-depth understanding of these geostructures and allowed them to identify the parameters that have the greatest impact on energy extraction. They were recognized with a Best Paper award for their comprehensive explanation of their work in the paper “Understanding the Thermal Efficiency of Energy Quay Walls: A Comprehensive Study Using Field Tests and Finite Element Simulations”.

Copper Laser Welding Process Stability

The final Best Paper award went to Julien Daligault, M. Dal, and S. Touzouirt of ENSAM and M. Sawannia, C. Hagenlocher, and R. Weber of the University of Stuttgart for their paper “Ray Optics and Mesh Adaption for the Study of Copper Laser Welding Process Stability Using COMSOL® Application Builder”.

Their paper focused on the use of multiphysics simulation for analyzing copper laser welding. Although the process is well understood for materials such as steel or titanium alloys, this is less true for the study of highly reflective and thermally conductive materials like aluminum or copper. The team developed a numerical model to understand the complex physical phenomena that occur during this type of laser welding.

Top 3 Posters

Simulating Under-Lake Infrastructure

The first of the three Best Poster winners were William van Sprolant of CvS Energies Sàrl and Daniel Bello-Mendes and Roland Rozsnyo of HEPIA for their poster on the hydrothermal potential of lakes. The poster showcases the team’s work within the ULISSE project, which focuses on developing an underwater tank that can store thermal energy from the surface of lakes and restitute it during the cold season. Before creating a full-sized tank, the team developed a small-scale mock-up and used the COMSOL Multiphysics® software to better understand the behavior of the system. Their model was in agreement with their physical tests results and its theoretical model calculation.

Investigating Crystalline Lens Inertial Overshooting

The second Best Poster award went to Ali Dahaghin, Milad Salimibani, Agnieszka Boszczyk, Agnieszka Jóźwik, and Damian Siedlecki from the Wroclaw University of Science and Technology for their poster on the investigation of inertial behavior of the crystalline lens. In this work, the team created a 2D model of a porcine eye in order to explore the mechanical responses of a crystalline lens when facing inertial overshooting. The team compared their model’s results with the results of ex vivo experiments, which showed good agreement. The results of both pointed to the importance of the damping system in absorbing forces acting on the lens.

Shock Testing a Sphere-Plate Collision

Spacecraft and their onboard equipment are often subject to strong dynamic loads in their missions. Particularly troublesome are severe high-frequency shocks that are typically caused by the activation of pyrotechnic devices. These shocks are transmitted to the entire structure and can be the cause of a failed mission.

Researchers Alessandro Daga, Luca Viale, and Luigi Lentini of the Politecnico di Torino explored this topic in their poster on the analysis of sphere-plate collision for shock testing, which earned them the final Best Poster award. In this work, they used simulation to better understand the contact dynamics of a plate pyroshock testing. They found their results were in line with their reference simulation model and were encouraged that these results could lead to improvements in the shock simulation field.
