Acoustic-Mechanic Modeling of Polydimethylsiloxane in the MHz Regime for Metamaterials Applications
Polydimethylsiloxane (PDMS) is a biocompatible material widely used in biomedical applications such as implantable sensors. A realistic modeling of PDMS in acoustic-mechanic simulation is useful especially for medical applications which use ultrasonic waves as interrogation source. ... Mehr lesen
Benefit of Vapor Consideration for LPBF Additive Manufacturing Process Simulation
Simulation of laser processes are more and more efficient. In some cases, as welding and additive manufacturing, the physical phenomena are complex, multi-physics and multi-phases, thus some assumptions have to be done. For Laser Powder Bed Fusion, a laser beam melts and vaporizes the ... Mehr lesen
Add-In ‘GoalSeeker’ – Advanced Parameter Optimization in Single and Combined Models
Simulations usually depend on a variety of parameters like geometric dimensions, process parameters, loads, or material properties. Typically, some of these parameters are fixed whereas others may be varied to obtain a special result. In many cases a simple sweep can be used to examine ... Mehr lesen
Using of General Extrusion Operator in Heat Transfer Applications
In this paper, the COMSOL Certified Consultant BE CAE & Test shows as the general extrusion operators can be successfully used to simulate thermal transfers in an industrial rotating furnace. Heat transfer in translating and rotating furnaces is a topic of high interest in several ... Mehr lesen
IAV’s Multi-Purpose 3D Coupling Solution for Electro-Physicochemical Battery Models via COMSOL API
The development of batteries for automotive application is progressing rapidly. It goes hand in hand with a rising demand for scarce raw materials. Diversification of cell chemistries is a promising approach to respond to market fluctuations and at the same time minimize system costs. A ... Mehr lesen
Electrochemomechanical Simulations of 3D-Resolved Solid-State Lithium-Ion Battery Cells
Solid-state batteries have emerged as a viable alternative to traditional liquid-based lithium-ion batteries, offering improved cost efficiency, safety, and environmental impact. Chlorine-rich lithium argyrodite (Li6PS5Cl) has emerged as a promising solid-state electrolyte, presenting ... Mehr lesen
Degassing of PP Pellets in a Silo: Keeping C9 Concentrations Below the Lower Explosion Limit
When polypropylene (PP) is produced it contains impurities in the form of dissolved gasses. These gasses can be removed by heating the material (in the form of pellets in a silo) and flushing with plenty of fresh air. However, one of the gasses is C9, which is flammable. We built a model ... Mehr lesen
Bubble Detachment from the Surface of a (Photo)Electrode
Many (photo)electrolytic devices involve the generation of bubbles (e.g., hydrogen, oxygen). In these devices, bubble coverage on the surface of the electrode not only decreases the active area, but also induces optical loss.[1,2] Efforts in understanding the bubble detachment process ...

Elastohydrodynamics of Roll-to-Plate Nanoimprinting on Non-Flat Substrates
Roll-to-plate nanoimprinting is a manufacturing method to replicate micro- and nanotextures on large-area substrates with UV-curable resins. Figure 1 shows a schematic of the roll-to-plate imprint process, which is considered in this study [1]. It uses several rollers, for imprinting and ... Mehr lesen
