CST Studio Suite 2025 SP5 Linux64 Tested Picture
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. Co-design with other SIMULIA products allows EM simulation to 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.
CST Studio Suite is available for both Windows and Linux. In the 2025 release, there are multiple improvements in the user experience when using Linux. For the complete list of features and improvements, please check the release notes included with the new release.
Onboarding and Examples
When using simulations to make design decisions, it is crucial that you have set up your model correctly. To support and educate users, CST comes with multiple ‘getting started’ books, and the component library now contains more than 500 ready-to-run simulation models. These models provide insights into what can be done in the latest version of CST Studio Suite and how to start with your modeling and simulation setup.
If you need further assistance, TECHNIA provides Dassault Systèmes-certified CST Studio Suite training and support.
Updates to Python CST apps
Even more Python CST apps are available in this latest release, bringing new features and enhanced performance. Many new methods are now available for writing your own Python scripts, especially when looking at PCB Studio and Design Studio (the schematic part of CST). When it comes to the 3D simulation studios/modules, most queries are available, including fetching results. 3D modeling is still done by embedding VBA code.
Antennas, RF components, and high-frequency solvers
Time domain solvers
- Floquet boundary condition to (narrowband) simulation of unit cell structures using T-solver
- Multiple simultaneous excitation lists can now be sequentially excited with the TLM solver
- Improved performance in the TLM discretizer and solver initialization for complex models
F-solver
- Performance improvements for the methods using tetrahedral mesh, in particular for curvature calculation during mesh generation and refinement
- Multi-frequency adaptive tetrahedral mesh refinement option for pre-defined frequency samples
- F-solver DDM (domain decomposition method)
- Further improved performance of the domain decomposition solver
- Automatic detection of similar domains for repetitions in the course of the domain decomposition solver start
Array task
- Time delay excitations for broadband beam steering
- Support to use existing array projects as subarray models
- ‘Simulation by zones’ is now also supported by the TLM solver
I-solver
- Adaptive surface mesh refinement
A-solver
- UTD (uniform theory of diffraction); higher-order contributions are now available
- Introduction of field source ports: Combined S-parameter and near-field surrogate model, enabling full IP protection. Allows for full far-field and S-parameter results in placement scenarios and advanced schematic-based workflows. Supported solvers for the placement domain include T-solvers (FIT, TLM) and the integral equation solver.
Additional design tools
- Antenna Magus, Filter Designer 3D, FEST3D, etc., are now included in the CST Studio Suite installer
- WASP-NET is now integrated into the SIMULIA ULM
- FEST3D includes a new exporting mode to CST Microwave Studio with CAD primitives, including parameters
EMC and EDA
- Importing PCBs is now quicker, especially on large boards. More control over details such as etch factor, solder mask, and more detailed via models. There are also feature improvements to operations such as bending PCBs.
Improved flexibility when using Python for PCB import. - When meshing advanced PCBs with tetrahedral mesh, this is now significantly faster.
- Another convenient feature for getting a quick overview of your board is the line impedance plot, which gives you a colormap plot showing the impedance along the selected traces. When using the thermal solvers, there are improvements in the electronics cooling ribbon for setting up fans, heat pipes, and field monitors.
- The pRLC solver now supports dispersive magnetic permeability, which might be of interest when modeling, for example, ferrites.
Low frequency
- There are additional feature enhancements on Litz wires.
- The low-frequency TD-solver now supports non-periodic linear motion scenarios that can be used when modeling, e.g., actuators.
