CST Studio Suite

Solvers

CST Studio Suite gives customers access to multiple electromagnetic (EM) simulation solvers which use methods such as the finite element method (FEM) the finite integration technique (FIT), and the transmission line matrix method (TLM). These represent the most powerful general purpose solvers for high frequency simulation tasks.

CST Studio Suite includes FEM solvers dedicated to static and low frequency applications such as electromechanical devices, transformers or sensors. Alongside these are simulation methods available for charged particle dynamics, electronics, and multiphysics problems.

The seamless integration of the solvers into one user interface in CST Studio Suite enables the easy selection of the most appropriate simulation method for a given problem class, delivering improved simulation performance and unprecedented simulation reliability through cross-verification.

Data Exchange Options

The excellent workflow integration available within CST Studio Suite provides reliable data exchange options which help to reduce the design engineer’s workload.

CST Studio Suite is renowned for its superb CAD and EDA data import capabilities. The sophisticated healing mechanisms, which restore the integrity of flawed or non-compliant data, are particularly important as even one corrupted element can prevent the use of the whole part.

Fully parametrized models can be imported and design changes are instantly reflected in the simulation model due to the bidirectional link between CAD and simulation. This means that the results of optimizations and parametric design studies can be imported back directly into the master model. This improves workflow integration and reduces the time and effort needed to optimize a design.

Antenna Modeling

The CST Studio Suite package can be used to develop both low-element and multi-element antenna arrays, as well as their related equipment, from the synthesis of individual elements to a complete design analysis, taking into account feeders and a protective casing.

Multi-channel antenna technology (MIMO, multiple-input, multiple-output) is widely used in modern mobile communication systems in order to obtain additional benefits from multipath propagation of radio waves and to improve signal reception in a complex environment, as well as the basis for building smart and cognitive systems. The CST Studio Suite includes a dedicated set of tools for determining MIMO antenna parameters such as spectral efficiency and envelope correlation.

For multi-element antenna array development, CST Studio Suite includes a wizard that greatly simplifies the design process. First, individual elements are modeled to calculate and optimize their impedance and radiation pattern, then a complete model of the antenna array is automatically generated and its electromagnetic modeling is performed, taking into account the mutual influence of elements and edge effects. Linking to array synthesis tools from the Antenna Magus software helps users find the appropriate array topology and how to power it.

Automatic Optimization

The performance of even the simplest device can be affected by a wide range of parameters. Optimization automates the process of adjusting the necessary variables in order to obtain values that meet the specified requirements. Built-in optimizers in all CST Studio Suite modules are applicable to adjust any parameter, including the geometric dimensions of the model, the properties of materials, as well as the shape of the excitation signal.

Global and local optimizers are available in CST Studio Suite. Local techniques search for solutions in the vicinity of the initial value of the parameter, so they are recommended for models that are close to optimal. Global techniques operate over a full range of parameters, making them much more practical than local optimizers for coarsely tuned models or complex structures.

Preliminary sensitivity analysis (sensitivity analysis) will significantly improve the work of the Trust Region Framework of the CST optimizer. This technique performs a quick assessment of the impact on performance of small changes in model parameters, providing important initial conditions for the optimizer to work. Sensitivity analysis will also allow you to evaluate, in just one computational cycle, the effect of manufacturing tolerances on changing the performance of a structure.

Microwave Filters

Filter design and optimization is one of the key areas of CST Studio Suite: the software contains a set of dedicated simulation tools for every stage of filter design, including initial topology synthesis, fine tuning, thermal detuning and high-frequency breakdown analysis.

The starting point in the filter design process is the correct specification. As a rule, design requirements are not limited to the description of pass and block frequencies, but include the definition of transmission and reflection zeros, Q-factor, ripple level in the passband, requirements for dimensions, thermal conditions and cost. In addition, a key task in the design process is the selection of an appropriate filter topology that meets the design requirements while still being within the established boundaries. In order to select the initial topology and obtain an appropriate model, the CST Studio Suite includes the Filter Designer 3D (FD3D) tool for synthesizing resonator filters and diplexers, taking into account cross-coupling mechanisms. The ability to extract the coupling matrix in FD3D allows you to efficiently tune 3D filter structures.

User Interface

The CST Studio Suite development environment is an intuitive user interface used by all modules. It includes an interactive 3D modeling tool, a circuit layout tool, a preprocessor for electromagnetic solvers, and post-processing tools tailored to industry needs.

The ribbon interface uses tabs to display all the tools and options needed to set up, run, and analyze simulations, grouped according to their position in the workflow. Contextual tabs mean that the most important task parameters are always just a click away. In addition, the Project Wizard and Quick Start Guide provide guidance for new users and offer access to a wide range of features.

The interactive 3D modeling tool underlying the interface uses the ACIS 3D CAD core. This powerful tool allows you to create complex models in CST Studio Suite and edit them parametrically with a simple WYSIWYG approach.
