CST Electromagnetic Co-Design Delivers Comprehensive Solutions
Electromagnetism is a driving force of progress in modern societies. All kinds of miracles happen once you put the plug into the outlet, or for that matter, hit the ON-switch. As we all know, it is not magical at all, but the result of precise engineering science. The foundations are the equations James Clerk Maxwell published 150 years ago which describe all electromagnetic phenomena. Although the equations can be noted down in very compact form, their application is —at almost all times—cumbersome. The solution is numerical simulation.
We at CST—Computer Simulation Technology AG, today take pride in delivering the most comprehensive solution for electromagnetic field simulation in the market. With a solver set that spans from statics to optical frequencies, and involves various simulation methods, CST STUDIO SUITE® enables access to a wide range of electro-magnetic applications through a single, user-friendly interface. With a customer base including market leaders in industries as diverse as telecommunications, defense, automotive, electronics and healthcare, CST STUDO SUITE is an indispensable tool in many R&D departments to meet specifications and deadlines predictably and efficiently. It is very likely that you own, use or benefit from devices and/or tools designed with CST software.
Besides classical Microwave & RF applications such as antennas or filters, the ability to simulate and optimize entire
electromagnetic systems has become increasingly important. This system view could include such aspects as the performance of an antenna installed in its operation environment, or the radiation safety of a patient in a High Field MRI coil, taking also into account the effect of heat transfer through the blood flow. Generally, the prediction of EMC/EMI compliance of the final product in a virtual prototyping state is a challenging application for electromagnetic simulation software that we help our customers overcome.
Electromagnetics is not an isolated effect. In the real world, electromagnetic fields can be coupled more or less strongly to other domains of physics, structural mechanics and thermodynamics in particular. We can define different Co-design methodologies based on the required exchange or physical quantities:
- In Collaborative Design, structural and EM teams work more or less independently. The designed product will have to comply with respective requirements.
- Concurrent Design requires a tighter communication and data exchange flow. Changes in one discipline might directly affect the performance of the device in the other.
- Multidisciplinary optimization requires access to all employed simulation methods consecutively, and can be organized on simulation management platforms.
- Finally, there is the full Multiphysics Co-simulation. If we look at induction heating for example: changes in temperature immediately affect the electric conductivity of the material and may lead to structural displacement. This requires the involved solvers to have direct and mutual access to the structure, mesh and field data in order to succeed.
In May 2015, we forged a partnership with Dassault Systèmes to integrate CST® 3D electromagnetic simulation technology into Dassault Systèmes’ 3DEXPERIENCE platform. This will enable customers to create and analyze electromagnetic behavioral models that simulate device function in a wide range of frequencies. This capability enhances the 3DEXPERIENCE platform’s simulation applications for solving multiphysics challenges in several areas including hybrid vehicle drivetrains and wearable electronics.
Since then, we have demonstrated workflows for Collaborative Design and Co-Simulation. We will continue to enhance all aspects of these Co-design methodologies in order to deliver the most versatile solution to the market.
