Veryst offers expert consulting services for product design, modeling, and simulation of electromagnetic devices, particularly their resistive, capacitive, and inductive properties.  We often employ advanced computational electromagnetics tools, analytical models, and laboratory testing to understand and validate complex electromagnetic behaviors.  Our experience modeling capacitive and resistive devices includes capacitive touch devices, dielectric sensors, bushing for high-voltage DC insulation, and the design of complex busbars and AC capacitors.

Veryst is experienced in a wide range of inductive simulations, including inductors; transformers; complex coils systems such as in MRI coils, voice coils, inductive (wireless) power transfer systems; and sensors (eddy current, proximity, etc.)  Our experience also includes inductive systems exhibiting motion and consisting of permanent magnets and nonlinear magnetic materials, such as rotating and linear machinery (motors, generators, magnetic gears, magnetic bearings, etc.), electromagnetic actuators, valves, and pumps that exhibit mechanical motion.  We accurately compute system parameters critical for designing electromagnetic devices, such as capacitance, inductance, resistance, system loss, force, torque, and efficiency.  Our clients use our calculations and recommendations to improve the performance of their existing products and to develop new products, in some cases resulting in new intellectual property. 

Veryst also offers expert consulting services for modeling the impact of other physical effects – such as heat transfer, structural mechanics, fluid flow, and acoustics – on electromagnetic devices.  For instance, we have coupled the heating and cooling analysis of transformers and motors with structural mechanics and acoustics for a noise and vibration analysis.

RF Tissue Ablation Simulation

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.

Equation-Based Modeling of Thin Shells for Electromagnetic Simulations

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.

Multiphysics Analysis of a MEMS Switch

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.
