Electrostatic and time domain simulations identify lightning attachment points and model current dispersion and heating effects. Cable solvers assess induced currents, impedance, and crosstalk in wire harnesses. Antenna placement studies ensure performance and minimize interference.
Transportation & Mobility
The automotive industry uses antenna design and placement studies to maximise the performance radars and navigation systems. Advanced simulations are also used with ADAS, Electrical motors ranges and with Litz wires for wireless car chargers.
High Tech
The integration and miniaturization of complex devices demand advanced simulations to ensure reliable performance. Signal and power integrity analyses verify proper data transmission and power delivery, while antenna optimization helps extend battery life. Electromagnetic compatibility (EMC) is also critical to prevent and withstand interference. All these factors can be effectively simulated using CST electromagnetic solvers.
Aerospace And Defense
Life Sciences
Due to limited measurement options inside the human body, simulations are vital for understanding electromagnetic field interactions. CST simulation software offers human body models to study imaging, treatment systems, and EM exposure risks. The CST computer simulation technology supports analysis of complex medical devices—from wearables to MRI systems—ensuring safe and effective design.
Benefits
Why use CST Studio Suite?
The value of simulations is a deeper understanding of your product. You can evaluate different design options before you’ve built your first physical prototype. This allows you to push boundaries, innovate and mitigate risk and cost.
Reduce costs
Efficient workflows and cooperation within the R&D team in combination with optimized product performance reduce cost and time-to-market. Import parametrized models and instantly reflect design changes in your simulation model by creating a bidirectional link between CAD and simulation. Minimizing the number of real-world prototype iterations saves costs in manufacturing, verification, and development teams.
Maximise R&D utilization
Make the most of R&D by implementing collaborative simulation throughout product development. Simulation allows you to evaluate your design as soon as your model’s complete. Simulations also work as an important troubleshooting tool, allowing you to perform quick assessments of product changes.
Accurate & efficient simulations
One of the most challenging aspects of simulations is to achieve results that are accurate enough in the shortest time possible. CST Studio Suite comes with a couple of full-wave solvers in both time domain and frequency domain, as well as numerous specialized solvers.Some solvers see a great speed-up factor when using GPU computing. There are also possibilities to use a hybrid approach where two full-wave solvers are coupled together to speed up the simulation. CST also offers the possibility to couple electromagnetic solvers with thermal solvers, enabling an exchange of power losses and temperatures between the solvers, providing multiphysics workflows.
Coupled 3D & circuit simulations
CST Studio Suite offers the possibility to couple 3D simulations with circuit simulations to properly calculate and visualize the field propagation of a subsystem. This allows you to, for example, match an antenna using lumped elements or to include the parasitic effects of your PCB while the transistors of a 3-phase inverter, described using SPICE models, are switched using PWM signals.
Automation & scripting
Python can be used for controlling CST Studio Suite. Python scripts can be run inside of CST Studio Suite to, for example, automate or support the modeling process, or an external Python interpreter/console can be used to control CST Studio Suite or extract results to use Python for post-processing.
Antenna design and optimization
Design and optimize antennas ranging from electrically large arrays and reflector antennas to miniature antennas printed on densely populated PCBs. Include the platform, housing, and radome to accurately calculate the installed antenna performance of the wireless system.
EMC (electromagnetic compatibility)
Combine 3D and circuit simulation to analyze the behavior of your subsystems. Using CST, both conducted and radiated phenomena can be investigated. This helps to identify and mitigate potential EMC problems early in the design process.
PCB analysis and design
Design and evaluate printed circuit boards with optimized workflows for power- and signal integrity analysis. CST imports board files from all major EDA tools, in addition to IBIS models.
Filters and RF components
Provides tools and solvers to synthesize filters and analyze highly resonant structures such as filters and multiplexers. Couplers, circulators, connectors, and cables can also be optimized using CST Studio Suite.
Photonics
Analyze the field propagation in photonic devices such as grating couplers, ring resonators, tapers, waveguides, and splitters to develop high-speed communication devices, sensors, or LIDAR systems.
Bioelectromagnetics
Bioelectromagnetics focuses on the interaction of electromagnetic fields and the human body. CST includes human body models, phantoms, and macros for simulation of biomedical and high-tech applications, such as implants, wearables, mobile devices, or medical imaging.
Lightning strike
In some industries, lightning strike simulations are crucial. CST includes an electrostatic solver, which can be used to find lightning attachment zones.
Magnet and coil design
CST is widely used for magnet design in, for example, electrical machines, MRI, NMR, particle accelerators, as well as magnetic shielding analysis. Simulate permanent magnets, resistive magnets and superconductive magnets with coupled EM/thermal/stress solvers
Electrical machines
Accurately model electromagnetic fields for various types of machines, including axial and radial flux topologies, as well as linear motion devices. Simulations include effects from iron and copper losses, eddy- and displacement currents, hysteresis, and demagnetization.
High voltage devices
Simulate traditional power electronics components such as transformers, bus bars, and insulators, as well as, for example, high power lines, wireless chargers, and coils using Litz wire technologies.
Sensors
Design capacitive, inductive, and magnetic sensors for applications including touch screens, equipment for non-destructive testing, and proximity sensors.
Charged particle dynamics
CST can also be used to design a wide range of charged particle applications ranging from accelerator devices, TWT (traveling wave tubes), magnetrons, and ion thrusters.
