CST market overview

CST offers products suitable for a wide range of electromagnetic design tasks, capable of simulating numerous components and systems.

Together, the products in the CST STUDIO SUITE® family can carry out electro- and magnetostatic, stationary, low-frequency and high-frequency simulations, as well as being able to calculate the effects of EM fields on substances as diverse as magnetic materials, biological tissues and charged particles. Tight integration with third party tools extends the application range even further.

The applications of CST software are almost limitless; among the devices that CST products have been used to simulate are couplers, filters, connectors, antennas, inductors, capacitors, PCBs, waveguides, travelling wave tubes, optical devices, sensors, actuators, electrical machines, SAR, MRI coils and cable harnesses, to name but a few.

Worked examples of applications of CST software are being added all the time. These can be found sorted by application area in the menu on the left, or through the site search at the top of each page.

Supporting Future Aircraft Certifications with EM Simulations

Supporting Future Aircraft Certifications with EM Simulations
Electromagnetic environments as, for instance, high intensity radiated fields (HIRF) and lightning can degenerate aircraft safe operation and even cause catastrophic effects without any precautions taken. The trend toward all-electric aircraft increases the number of aircraft functions performed by avionics. The risk of failure is even higher for modern aircraft with structures made of carbon-fiber composites (CFC). Read full article..

Accuracy in Simulation with CST STUDIO SUITE 2016

Accuracy in Simulation with CST STUDIO SUITE 2016
CST® STUDIO SUITE® is an electromagnetic simulation tool used to design, analyze and optimize devices and systems at all stages of the development process. It is used in industries as diverse as electronics, automotive, aerospace, medical and energy, and covers the electromagnetic spectrum from statics to optics. By replacing physical prototypes with virtual ones, engineers can study how their products work at the earliest stages of design and reduce the number of physical models that need to be constructed. For virtual prototyping to be a viable option, the simulation tools need to be accurate without sacrificing performance. For this reason, the release of CST STUDIO SUITE 2016 builds on the success of previous versions with a range of new features that make the analysis of systems more powerful while building on CST’s reputation for accuracy.

Electromechanically-coupled simulation of a Coaxial Magnetic Gear with multiple rotational moving gaps

Electromechanically-coupled simulation of a Coaxial Magnetic Gear with multiple rotational moving gaps
Magnetic gears are an attractive alternative to mechanical gears since they are contact-free, silent and more reliable. An application of such gears is to increase the torque density in electrical machines. This article demonstrates features useful for the simulation of such magnetic gears and other electromechanical components with CST EM STUDIO®. Transient analysis of the gear, in essence two synchronous machines, eliminates the tedious need to determine the load angle between the moving rotors. Read full article..

Optimization of Torque in a Permanent Magnet Synchronous Motor (PMSM) for Traction Applications

Optimization of Torque in a Permanent Magnet Synchronous Motor (PMSM) for Traction Applications
This article summarizes the simulation and optimization of a Permanent Magnet Synchronous Motor (PMSM) commonly used for traction in automotive and transportation systems. The goal is to optimize two conflicting goals - maximize the average torque and minimize torque ripple. The permanent magnet geometry, radial position, angular orientation as well as the barrier shapes were, amongst others, used as variables in the optimization. Read full article..

High-power microwave devices with CST STUDIO SUITE: Simulation of double-gap vircator with feedback

High-power microwave devices with CST STUDIO SUITE: Simulation of double-gap vircator with feedback Document type
Devices which generate high-power microwaves due to the interaction of electron beams with electromagnetic fields can be simulated with CST PARTICLE STUDIO® (CST PS), a package of CST STUDIO SUITE®. The fully relativistic, self-consistent particle-in-cell solver, including full space charge effects, is used to simulate a virtual cathode oscillator (vircator). The simulation aids understanding and gives insight into the physics governing the operation of the device. The general level of sensitivity of the device is evaluated for different prospective variable parameters. The ones which cause a significant variation in device operation or efficiency are then used as input for the optimizer in order to find the best parameter sets for maximum efficiency at different frequencies of interest.

CST EMC for Electronics Flyer

CST EMC for Electronics Flyer Document type
Electromagnetic compatibility (EMC) is an integral part of the development of any electronic device. By law, products must comply with international EMC standards which regulate EM emissions and the susceptibility of electrical and electronic systems in order to be sold. A successful product must strike a balance between EMC and competing design requirements such as size, cost and performance, and this can pose major challenges to engineers. The earlier a potential EMC problem is identified, the less disruption it causes to the design process. By including EMC compliant design at an early stage, additional costly development iterations can be avoided later on. Simulation using the CST EMC STUDIO® software package – a module of CST STUDIO SUITE® – allows problems to be identified and corrected from the start of the design process before the first prototype is even built. The software includes a range of solvers, ranging from PCB design rule checkers to full-wave 3D solvers to specialized cable and PCB solvers, which can be linked and hybridized with the CST® System Assembly and Modeling (SAM) framework.
