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.

25+ EM Simulation Solvers

CST Studio Suite contains:

  • 9 high frequency solvers
  • 5 low frequency solvers
  • 4 multiphysics solvers
  • 3 particle dynamics solvers
  • 3 EDA & EMC solvers
  • Opera, the powerful standalone low frequency electromagnetic, electromechanical, and multiphysics solver
  • Two-way SOLIDWORKS/PTC Creo CAD integration

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.

cst cable studio modeling

Intuitive, fully parametric model and cable construction within the simulation environment.


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 modelswith 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.

Hardware acceleration

CST solvers will engage with CPU multithreading, GPU acceleration, and distributed and MPI cluster computing.
