A market-leading electromagnetic field software
Electromagnetic Field Software
High-performance 3D EM analysis for designing, analysing and optimising electromagnetic components and systems.
CST analyses Electromagnetic systems from statics and low-frequency to high-frequency range, in a fully parametric design environment.
CST holds specialised solvers for applications such as motors, circuit boards, cable harnesses and filters
CST provides coupled simulation: System-level, hybrid, multiphysics, thermal, EM/circuit co-simulation, and co-simulation with Abaqus
CST allows workstation multithreading, GPU and hardware acceleration, and cluster distributed computing and MPI.
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. Additional solvers for specialist high frequency applications such as electrically large or highly resonant structures complement the general purpose solvers.
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 PCBs and Packages Module of CST Studio Suite is a tool for signal integrity (SI), power integrity (PI), and electromagnetic compatibility (EMC) analysis on printed circuit boards (PCB). It integrates easily into the EDA design flow by providing powerful import filters for popular layout tools from Cadence, Zuken, and Altium. Effects like resonances, reflections, crosstalk, power/ground bounce and simultaneous switching noise (SSN) can be simulated at any stage of product development, from pre-layout to post-layout phase.
CST Studio Suite includes pre-defined workflows for IR drop, PI and SI analysis. Applications like; high-speed PCBs, Packages, Power electronics.
Rule Check is an EMC, SI and PI design rule checking (DRC) tool that reads popular board files from Cadence, Mentor Graphics, and Zuken as well as ODB++ (e.g. Altium) files and checks the PCB design against a suite of EMC or SI rules. The kernel used by Rule Check is the well-known software tool EMSAT. The user can designate various nets and components that are critical for EMC, such as I/O nets, power/ground nets, and decoupling capacitors. Rule Check relieves the tedium and removes the human error by examining each critical net in turn to check that it does not violate any of the selected EMC or SI design rules.
After the rule checking is completed, the EMC rules’ violations can be viewed graphically or as an HTML document. Applications like; Electromagnetic compatibility (EMC) PCB design rule checking, Signal integrity and power integrity (SI/PI) PCB design rule checking.
The CST Cable Harness Solver is dedicated to the three-dimensional analysis of signal integrity (SI), conducted emission (CE), radiated emission (RE), and electromagnetic susceptibility (EMS) of complex cable structures in electrically large systems.
Applications like; General SI and EMC simulation of cables, Cable harness layout in vehicles and aircraft, Hybrid cables in consumer electronics.
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. Integrations with CATIA, SOLIDWORKS & 3DEXPERIENCE Platform are possible.
CST Studio Suite offers automatic optimization routines for electromagnetic systems and devices. CST Studio Suite models can be parameterized with respect to their geometrical dimensions or material properties. This enables users to study the behavior of a device as its properties change. Users can find the optimum design parameters to achieve a given effect or fulfill a certain goal. They can also adapt material properties to fit measured data.
The CST Studio Suite design environment is an intuitive user interface used by all the modules. It comprises a 3D interactive modeling tool, a schematic layout tool, a pre-processor for the electromagnetic solvers and post-processing tools tailored to industry needs.
The ribbon-based interface uses tabs to display all the tools and options needed to set up, carry out and analyze a simulation, grouped according to their position in the workflow. Contextual tabs mean that the most relevant options for the task are always just a click away. In addition, the Project Wizard and the QuickStart Guide provide guidance to new users and offer access to a wide range of features.
The 3D interactive modeling tool at the heart of the interface uses the ACIS 3D CAD kernel. This powerful tool enables complex models to be constructed within CST Studio Suite and edited parametrically with a simple WYSIWYG approach.
Electromagnetic field solvers for applications across the EM spectrum are contained within a single user interface in CST Studio Suite. The solvers can be coupled to perform hybrid simulations, giving engineers the flexibility to analyze whole systems made up of multiple components in an efficient and straightforward way.
CST allows to be used in co-design with other SIMULIA products so that EM simulation can be integrated into the design flow and drives the development process from the earliest stages.
Common subjects of EM analysis include the performance and efficiency of antennas and filters, electromagnetic compatibility and interference (EMC/EMI), exposure of the human body to EM fields, electro-mechanical effects in motors and generators, and thermal effects in high-power devices.
