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.

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.

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. The steady-state, average torque and ripple, obtained from min/max values of torque, were used as the optimization goals. Read full article..

Antenna and Propagation Simulation with CST STUDIO SUITE and WinProp

Antenna and Propagation Simulation with CST STUDIO SUITE and WinProp Document type
This Application Note describes how the CST® STUDIO SUITE® software package can be linked to WinProp to simulate the radiation characteristics of an antenna and its performance in a complex indoor or outdoor environment. The full-wave 3D solvers in CST STUDIO SUITE are used to the design and simulation of the antenna itself, while the wave propagation methods in WinProp use the calculated radiation pattern to calculate coverage in an electrically large environment.

Electromagnetic Simulation of a Shaded-Pole Induction Motor

Electromagnetic Simulation of a Shaded-Pole Induction Motor
Shaded-Pole Induction Motors, used mainly in household and low power applications, are renowned for their simplicity, low cost and robustness. They are also, however, notorious for their low effciency and low starting torque. To counteract some of these shortcomings, finite element simulation can be applied to improve some of the critical parameters of such motors. This is extremely usefuls since, in contrast to other motor types, there is no accepted standard for the equivalent circuit of such motors. This article demonstrates the capabilities of CST EM STUDIO® for this purpose. Due to the strong non-linear magnetic fields and eddy current effects in the shaded poles and rotor cages, the transient LT solver with motion is applied. Read full article..

RFID And Wireless Power Transfer Simulation From Tag to System

RFID And Wireless Power Transfer Simulation From Tag to System Document type
This article discusses the design and modeling of both low frequency (LF) and high frequency (HF) RFID devices using CST® STUDIO SUITE®. This can be done at the level of the individual tag, but also for the entire system, including the reader, the tagged object and its surroundings. Analyzing the entire system with simulation allows the suitability of the chosen RFID system for the application to be investigated, and can reveal unforeseen interactions that can be hard to identify with measurement alone.
