CST Studio Suite - Complete Technology for Electromagnetic Simulation

How do you know your design will work before expensive physical prototyping?

High-performance simulation.

CST Studio Suite is high-performance electromagnetic simulation software for design, analysis, and optimization.

Virtual prototyping cuts down on the costs of R&D by shortening the iteration cycle, identifying and addressing design flaws early in development, and bringing parts to market faster.

As a leading technology of engineering companies around the world, CST Studio Suite provides a set of electromagnetic simulation solvers built with accuracy, speed, and usability in mind.

There's a Solver for That

What is an efficient solver for one scenario may not be so for another.  Therefore, the solvers included in CST Studio Suite offer both general and purpose-built solutions for all applications -- frequency ranges from statics to optics, and physical sizes from nanoscale to electrically enormous.

25+ Solvers

CST Studio Suite contains:

  • 9 high frequency solvers
  • 5 low frequency solvers
  • 4 multiphysics solvers
  • 3 particle dynamics solvers
  • 3 EDA & EMC solvers

Working Together

Some complex, multi-component systems may require multiple solvers to maximize computational efficiency. CST can do that. Some assemblies may require multiple solvers to account for structural and thermal considerations. CST can do that.

With its System Assembly and Modeling (SAM), CST Studio Suite offers a single user interface for multisolver and multiphysics simulation. Engineers can test designs in complex scenarios, at optimal solver speed, involving many factors to quickly gain a fuller picture of component performance before parts enter the manufacturing phase of development.

Accessibly Packaged

Solvers are bundled into CST modules according to purpose, such as CST Microwave Studio, CST EM Studio, CST PCB Studio, CST Particle Studio, CST Cable Studio, and more.

Simulation Setup Made Easy

CST Studio Suite's design environment puts ease-of-use at the forefront while retaining a rich feature set for creating a variety of electromagnetic simulation models.


Users can construct and edit simulation models using CST Studio Suite’s powerful parametric CAD interface. It supports all the major CAD and Electronic Design Automation (EDA) options and then some. SOLIDWORKS users can enjoy a direct two-way link in their CAD operations. Whatever your software choices, you can expect a smooth transition between workspaces.

EM simulations apply to many substances, including magnetics, photonics, and biological physics, which each display unique characteristics. CST Studio Suite includes the material models necessary to simulate a wide range of electromagnetic phenomenon, including plasmonic and photonic effects, ferromagnetism, secondary electron emission, and biological heating.

Body models

An accurate model of the human body is critical to many EM fields, especially in healthcare and life sciences. CST Studio Suite includes both voxel-based and CAD-based body models with detailed internal structure and realistic EM and thermal properties.


The fast, accurate meshing provided by CST Studio Suite offers mesh refinement and automatic adaption to increase mesh quality in key parts of the model. Proprietary Perfect Boundary Approximation models even the most complex CAD data, even for models with billions of mesh cells.


CST Studio Suite provides users with an array of synthesis tools to automatically build models of potential designs for planar and cavity filters, antennae, antenna arrays, and waveguides.
