|High Frequency Solvers|
|Time Domain||This solver calculates the development of fields through time at discrete locations and at discrete time samples, which is remarkably efficient for most high-frequency applications and can obtain the entire broadband frequency behavior of the simulated device from a single calculation.
CST includes two time domain approaches, Finite Integration Technique (FIT), similar to FDTD, as the flagship solver with 40+ years of research, and the Transmission Line Method (TLM) for more EMI/EMC applications.
This solver utilizes the finite element method (FEM) with advanced tetrahedral meshing to solve Maxwell’s equations in the frequency domain. While a classical frequency-domain simulation would be calculated frequency-by-frequency, CST employs two broadband methods, one for general purpose and one reduced-order for high-Q structures.
|Eigenmode||Used to calculate the frequencies and corresponding electromagnetic field patterns (eigenmodes) when no excitation is applied. Losses with the assumption of a frequency-independent complex permittivity or reluctivity are available. If waveguide ports are used, energy may leave the device through those terminals.|
|Integral Equation||The integral equation solver discretizes the object boundary using the multilevel fast multipole method (MLFMM) which applies for the special interest of electrically large models.|
An asymptotic computation is an analysis in the frequency domain based on a so-called ray-tracing (shooting and bouncing rays, SBR) technique, typically used for scattering or antenna placement for electrically very large domains.
|Multilayer||A 3D solver for planar modeling and analysis based on the method of moments (MoM). It enables users to simulate multilayer geometries accurately and efficiently.|
|Partial RLC||Used for calculation of equivalent circuit parameters, i.e., partial inductances, partial resistances, and partial capacitances, for a specified model. The extraction is based on the Frequency Domain Solver.|
|Low Frequency Solvers|
|Low Frequency – Frequency Domain (LF-FD)||A 3D solver for simulating the time-harmonic behavior in low frequency systems that is useful for simulations of coils used for wireless power transfer.|
|Low Frequency – Time Domain (LF-TD)||A 3D solver for simulating the transient behavior in low frequency systems which include eddy currents, non-linear effects and motion. Resistive-capacitive effects may also be modeled.|
|Electrostatic||A 3D solver for simulating static electric fields.|
|Magnetostatic||A 3D solver for simulating static magnetic fields.|
|Stationary Current||A 3D solver for simulating the flow of DC currents through a device, especially with lossy components.|
|Steady State Thermal
||Calculates the stationary temperature distribution of a system. Heat sources can include electric and magnetic fields, currents, particle collisions, human bio-heat, and other pre-defined sources.|
|Transient Thermal||Calculates how a system heats over time. Heat sources can include electric and magnetic fields, currents, particle collisions, human bio-heat, and other pre-defined sources.|
|Conjugate Heat Transfer||Combines thermal and fluid dynamics simulation methods, and can calculate the heating of a device while taking convection and fan cooling into consideration.|
|Mechanical||Offers linear and non-linear methods for calculating the displacement and deformation of structures.|
|Particle Dynamics Solvers|
|Particle-in-Cell||A versatile, self-consistent simulation method for particle tracking that calculates both particle trajectory and electromagnetic fields in the time-domain, taking into account the space charge effects and mutual coupling between the two.|
|Particle Tracking||A 3D solver for simulating particle trajectories through electromagnetic fields.|
