By keeping these three concepts at its core, CST STUDIO SUITE has become widely used by engineers, designers and researchers
working in many fields, including microwaves & RF, optical devices, electronics, electromagnetic compatibility (EMC), particle
dynamics and low frequency design. To learn about some of the applications that CST STUDIO SUITE has been used to simulate,

Numerical simulation discretizes the structure onto a mesh. Each additional cell increases the computational requirements of the simulation, which means that it is advantageous if the mesh accurately describes the model while using as few mesh cells
as possible. CST STUDIO SUITE includes hexahedral, tetrahedral and surface meshes,
with different approaches suitable for different situations.

CST offers a multitude of hardware-based simulation acceleration options, such as multithreading, GPU computing, MPI
cluster computing and distributed computing. These can be
used to improve the computational performance of a computer, or to divide the workload between multiple nodes in a
network or cluster. These high-performance computing (HPC)
methods are available for almost every type of application
and hardware configuration, ranging from individual workstations to enterprise-level clusters.
In order to help make the most of investments and make it
easier to choose the most effective acceleration solution for
a given simulation model, CST uses an acceleration token
licensing scheme. This enables greater versatility in accessing
and combining high-performance computing options,
allowing acceleration methods to be mixed and matched.
For small businesses with big requirements,
CST STUDIO SUITE can also be run in the cloud.
With cloud computing, models can be transferred
securely over the internet to the HPC computing
provider and the calculations carried out using their
hardware. This means that users who occasionally
have very demanding simulations to run can access
HPC without the cost of installing and maintaining
dedicated hardware.

System Assembly and Modeling (SAM) simplifies the management of simulation projects in CST STUDIO SUITE. A device
may consist of more than one component, each of which may
work best with a different solution method, or might require
several linked simulation and processing stages to produce the
data the user needs. SAM provides a framework for carrying
out simulations and optimizations of entire systems efficiently.
The various elements of a reector antenna are each best solved by different
simulation methods: the orthomode transducer by the frequency domain solver,
the horn antenna by the time domain solver, and the reector dish by the
integral equation solver.

CST STUDIO SUITE is used in industry and academia across a wide range of fields and application areas, to simulate everything
from consumer devices, to nanoscale structures, to the human body. The most common applications can be divided into the five
fields shown above. For each field, CST STUDIO SUITE contains tools for designing, simulating and optimizing devices and systems.

The simulation of high frequency electromagnetic fields, ranging from RF up to optical frequencies, is one of CSTs core competencies. The array of microwave & RF and optical systems to
which CST STUDIO SUITE has been applied is massive, and includes the design of antennas, filters, connectors, power splitters, microwave ovens, medical devices, metamaterials, optical
components and photonic crystals.
The fields around electrically large structures such as ships,
aircraft and buildings can be simulated effectively at RF and
microwave frequencies, and in very complex structures such
as the human body. CST STUDIO SUITE can also be used to
analyze the properties of a device for example,
Current distribution on the metallic surface of a 155 m long ship excited by a plane wave of 400 MHz:
the relative permittivity (81) and conductivity (0.01 S/m) of salt water are considered in the simulation.

EMC / EMI
Electromagnetic compatibility (EMC) and electromagnetic interference (EMI) are two sides of the same coin. For EMC compliance, the device under test must not produce conducted or
radiated emissions that can disrupt other devices, while for
EMI immunity, the device must be able to withstand expected
interference, whether from nearby devices or from environmental electromagnetic effects (E3) such as lightning strikes or
electromagnetic pulse (EMP).
EMC / EMI
EMC/EMI and E3 problems can arise from seemingly insignificant details in a complex structure for instance, a cable, a
vent or a seam. The transmission line matrix (TLM) solver is
very suitable for these situations, and supports compact models that can efficiently model complex structures.
Cables can pick up fields emitted in one part of the structure,
conduct them to another part, and then re-radiate them,
causing further EMI problems. The time domain solvers can
be supplemented with hybrid transient cable simulation.
This allows analytical cable and cable harness models to be
integrated into the 3D model.

Particle Dynamics

PARTICLE DYNAMICS
CST has been used in particle accelerator facilities since its earliest days. CST STUDIO SUITE includes several tools for designing charged particle devices ranging from microwave devices
such as magnetrons and electron tubes to ultrarelativistic components for particle accelerators.
For particles in static fields, the particle tracking solver with
gun iteration can quickly calculate their trajectory through
the device, making it a useful tool for electron gun design. The
particle-in-cell (PIC) solver meanwhile takes into account the
fields produced by the particles, and is suitable for devices such
as magnetrons, klystrons and traveling wave tubes (TWT), as
well as for multipaction analysis. GPU acceleration can be used
to improve the performance of the PIC solver further.
To help with component design, the wakefield solver calculates the fields around particle bunches travelling through the
accelerator. These particles produce wakefields when passing
through structures such as collimators and beam detectors, and
these can disrupt the beam. For components with a very high Q
factor, such as accelerator cavities, the eigenmode solver offers
a quick calculation of the resonant modes of the cavity these
can then be used as the basis of a PIC simulation.

CST EM STUDIO is now an integral part of the development process of various power
transformer components at Siemens (Energy). This is especially a consequence of the
intuitive user-interface and the variety of available solvers.
Low frequency simulation is also useful for designing magnetic devices. Coils and magnets can be defined easily, and
non-linear materials such as ferromagnets are supported.
CST STUDIO SUITE can calculate not only the fields within
the device, but also the forces and torques acting on the
various components. These features can be used to design
motors, generators, actuators and sensors.
