Time, frequency and specialized solvers cover different electromagnetic problem classes
The Time Domain Solver handles transient 3D full-wave work with FIT and TLM implementations and can cover broadband behavior in a single run. The Frequency Domain Solver uses FEM for resonant structures and multi-port systems. Integral Equation and Asymptotic solvers extend the same environment to electrically large structures, installed antenna performance and scattering problems.
Static and low-frequency solvers cover electric and magnetic field problems in motors, generators, transformers, sensors and power equipment. Solver choice can therefore follow the physics and electrical size of the model instead of forcing every problem into one numerical method.
SAM and the Hybrid Solver Task connect component models into system-level EM workflows
System Assembly and Modeling (SAM) manages linked component simulations through schematic modeling and can pass fields, currents and S-parameters between stages. This supports systems in which different components need different simulation methods.
The Hybrid Solver Task directly links the Time Domain, Frequency Domain, Integral Equation and Asymptotic solvers. It is useful when a detailed antenna or component has to be analyzed together with a much larger surrounding structure without solving every part with the same method.
PCB, cable and EMC solvers extend the model into SI/PI and interference analysis
CST Studio Suite includes PCB, cable and EMC workflows for signal integrity, power integrity, emissions and susceptibility analysis. PCB solvers cover transmission-line, PEEC and 3D finite-element approaches, while cable and EMC tools extend the analysis to harnesses and device-level interference problems.
2019, 2021, 2023 and 2026 introduce distinct array, modeling and optimization changes
| Release breakpoint | Buyer-relevant local change |
|---|---|
| CST Studio Suite 2017 | Baseline offered family for the multi-solver electromagnetic workflows that later releases expand. |
| CST Studio Suite 2019 | SAM Array Task adds full-array post-processing optimization, and the release adds a new Schematic Editor. |
| CST Studio Suite 2021 | Geometry wrap and projection operations are added, along with conversion between Discrete Ports and Lumped Elements. |
| CST Studio Suite 2023 | Filter Designer 3D is expanded, and subarray simulations gain easier setup and excitation. |
| CST Studio Suite 2026 | Non-parametric optimization is expanded, with a preview shape-reconstruction step for follow-up modeling and optimization. |
Broad-spectrum CST simulation and low-frequency Flux analysis serve different EM jobs
CST Studio Suite spans general-purpose high-frequency, low-frequency, particle, EMC and EDA solvers from statics to optical frequencies. Altair Flux is finite-element software centered on low-frequency electromagnetic and thermal analysis for devices such as motors, sensors and actuators.
If the project is centered on that low-frequency finite-element workflow rather than CST's broader multi-solver electromagnetic environment, see Altair Flux.
