Join us and register for the COMSOL Day Austria online event.
We invite you to a day of multiphysics modeling training, inspiring practical presentations and discussions – from your office or home office.
Expect inspiring keynote talks and discussions, as well as interesting COMSOL presentations on modeling techniques for various industry and research areas. You can ask questions at any time and the speakers will be happy to answer them.
In the Tech Cafés, you become active yourself and exchange ideas with colleagues and COMSOL engineers about your simulation projects and discuss things you've always wanted to talk about. You are welcome to prepare yourself for this! Specific questions about licensing options or modeling issues that you'd rather discuss privately with COMSOL staff can be addressed in one-to-one meetings at any time during COMSOL Day.
Learn the fundamental workflow of COMSOL Multiphysics®. This introductory demonstration will show you all of the key modeling steps, including geometry creation, setting up physics, meshing, solving, and postprocessing.
See how you can deploy the power of high-fidelity simulation to engineers, designers, operators, and scientists throughout your organization.
Multiphysics Simulation for Optimization of Piezoelectric Transducers and Micro-/Nanoimprint Processes
I will give you insight into how COMSOL Multiphysics® helps us optimize the design and properties of piezoelectric transducers for sensing and energy harvesting in different use cases. You will also learn how we apply microfluidic simulations to improve roll-to-roll micro- and nanoimprint processes for functional surfaces.
Design Optimization of a PZT MEMS 1D Micromirror for High-Resolution Displays
Micromirrors can be used in many fields, including light detection and ranging (lidar) systems for the automotive industry or biology for endoscopic bioimaging. Compared to well-established electrostatic and magnetic micromirrors, piezoelectric micromirrors can offer better electric power efficiency and better miniaturization abilities. In this work, we optimized a piezoelectrically actuated silicon-based MEMS micromirror for high-resolution displays. Our design relies on a previous device from Baran et al.  and is specifically optimized to increase its optical scan angle (θopt) and reduce its power consumption compared to the original design.

Computational fluid dynamics (CFD) simulations are used in numerous fields of industry and research. This Tech Café is your platform to discuss and exchange experiences with colleagues and COMSOL engineers on issues such as turbulence models, flow regimes, and multiphase flows.
Learn about the modeling tools available in COMSOL Multiphysics® to simulate piezoelectric devices such as transducers, actuators, and harvesters. We will go over the modeling steps required for piezoelectric simulations and multiphysics couplings such as coupling with pressure acoustics as well as coupling with fluid flow and electrical circuits.

You can also ask questions about specific applications involving multiphysics phenomena such as acoustic-structure interactions, fluid-structure interactions, thermal stresses, and more.
Learn about using the Ray Optics Module and Wave Optics Module for optics and photonics applications.
Sensitivity analysis can be used to identify important parameters that can then be changed manually or automatically using optimization. Optimization of these parameters enhances the performance of your product. In the case of manufacturing uncertainties, it is possible to compute several objectives and optimize for the worst of them. You will see several examples of how optimization can be set up in the COMSOL® user interface.
Probably no other physical quantity has such an important influence on so many different model parameters as temperature. Therefore, in this Tech Café, you can discuss with colleagues and COMSOL staff the simulation of heat transport by convection, conduction, and radiation, as well as the influence on other physical or chemical processes.
Design of Metasurfaces
One can design optical components by engineering features with the same order of magnitude as the light wavelength. In this talk, we want to present strategies for how to design and simulate such structures. We will show examples of implementable structures and how to estimate and evaluate their optical performance.
Design and Implementation of a Photonic Nanomechanical Interface Between Gigahertz and Telecom Frequencies
Transducers connecting different frequency regions are a hot topic in the current quantum information community due to their potential to enable long-distance quantum networks. While there are a variety of approaches to achieve such a frequency conversion, using a mechanical resonator has been proved to be the most efficient method so far. In this talk, we will show how we designed and optimized a nanomechanical resonator, which converts photons between an optomechanical cavity operating at infrared wavelength and a microwave resonator. Our integrated device excels in the high conversion efficiency and the required ultralow pump powers in the picowatt regime.
