CST STUDIO SUITE Examples

CST STUDIO SUITE® is a collection of electromagnetic simulation software. It is an integrated design environment that contains tools for the design and optimization of devices in a wide range of frequencies from static to optical. CST Studio Suite® gives customers the choice of multiple powerful solver modules, including modules based on numerous different methods including finite element method (FEM), method of moments (MoM), multilevel fast multipole method (MLFMM) and shooting boundary ray (SBR), each offering distinct advantages in their own domains.

CST STUDIO SUITE contains various modules. We are currently supporting the following modules in batch: CST MICROWAVE STUDIO® (MWS), CST EM STUDIO®, CST PARTICLE STUDIO®, and CST MPHYSICS STUDIO®. With Rescale's scalable compute workflow, users can run conveniently run CST SUDIO SUITE models on multiple cores to achieve low run times.

CST MICROWAVE STUDIO

CST MICROWAVE STUDIO® is a specialist tool for the 3D EM simulation of high frequency components. CST MWS' unparalleled performance is making it first choice in technology leading R&D departments. The flagship modules include Time Domain solver and Frequency Domain solver.

CST EM STUDIO Example

CST EM STUDIO® (CST EMS) is dedicated to the simulation of static and low frequency devices. Embedded in the same CST user interface, CST EMS features a variety of solver module to tackle electrostatics, magnetostatics, current flow and low frequency problems, and can be coupled to other CST STUDIO SUITE® modules for charged particle and multiphysics simulations.

Applications include: actuators, brakes, EMC, generators, motors, sensors, transformers measurement instrumentation, and shielding effects.

This is an example of an electromagnetic radiation simulation through an RJ45 connector. A 1V potential is applied to the end of RJ45 contacts. Every other wire is connected to a metallic ground plane.

This model used 198,240 mesh cells. The electric potential through the RJ45 connector is shown below.

CST PARTICLE STUDIO Example

CST PARTICLE STUDIO is a specialist tool for the fast and accurate analysis of charged particle dynamics in 3D electromagnetic fields. Powerful and versatile, it is suitable for tasks ranging from designing magnetrons and tuning electron tubes to modeling particle sources and accelerator components.

The particle tracking solver can model the behavior of particles through static fields, and with the gun iteration, space charge limited emission. The particle-in-cell (PIC) solver, which works in the time domain, can perform a fully consistent simulation of particles and electromagnetic fields. For relativistic applications, the wakefield solver can calculate how the fields generated by particles traveling at (or close to) the speed of light interact with the structure around them.

This is an example of a stationary particle tracking solution in an electromagnetic field. This model used 150,336 mesh cells. The trajectories of charged particles from a multibeam gun emitter is shown below.
