Magnetic actuators use electromagnetic fields to generate motion or force, playing a crucial role in various engineering applications. This webinar explores the design and simulation of magnetic actuators, focusing on fundamental principles, material selection, and performance optimization. It covers modeling techniques and computational analysis to evaluate actuator behavior, efficiency, and force generation, providing insights into developing high-performance solutions.
Axial permanent magnet couplings are electromagnetic devices that transmit torque from a primary driver to a load without mechanical contact. Veryst used a finite element analysis (FEA) model to analyze the complex coupling nature of these magnetic devices to maximize the torque transmission
Manufacturing variations are of critical importance in MEMS design. In this MEMS gyroscope case study, Veryst created an approach to look at the effect of a range of manufacturing variations on MEMS devices using the same mesh. We also use semi-analytic equations to enable scalable modeling of the gyroscope electrostatic actuation and pick-off (which senses the motion produced by rotation).
For several of the electromagnetics interfaces provided with COMSOL Multiphysics, a single layer shell feature, the “Transition Boundary Condition,” is available. Veryst created custom expressions to extend this feature for multiple layers. In this case study we discuss the implementation of this new functionality, and the advantages of using such shells for electromagnetic modeling.
MEMS mirrors raster the laser beam in many next-generation LiDAR system designs. Constructing a finite element model of a MEMS mirror is challenging, as it is difficult to represent the large number of comb fingers in the comb drives that actuate these devices. Veryst addressed this problem by using mixed analytic and finite element approaches to construct accurate finite element models.
The responses of a MEMS switch immersed in fluids differs from that in a vacuum. Veryst Engineering developed a coupled electrostatic-fluid-structure interaction model to investigate the switch response time, deformation, and energy dissipation.
Radio frequency tissue ablation is a commonly used and minimally invasive tissue treatment procedure. Accurately modeling this kind of coupled multiphysics problem is often challenging. Veryst developed a COMSOL Multiphysics model accounting for heat transfer, electric field, and fluid flow to study the RF tissue ablation problem where an electrode is targeting a tissue close to a blood vessel.
