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.


CST Studio Suite's huge solver array and co-simulation capabilities make it suitable for a wide variety of applications, including antennas, microwaves & RF, biological EM, optical, EDA/electronics, EMC/EMI, particle dynamics, statics/low frequency, and coupled thermal and structural multiphysics.

Accelerated Computing

CST Studio Suite scales to the highest-end workstation CPUs, GPUs, and distributing computing setups.

Additionally, a base CST license will support parallelization across all cores of your first two CPU sockets with no additional license purchases necessary.
