Main Features

Welcome to CST CABLE STUDIO, the specialized tool for the analysis of conducted transmission,EMI (Electromagnetic Interference) and EMS (Electromagnetic Susceptibility) on complex cable structures.

Main Features of CST CABLE STUDIO

A smart user interface that makes it easy to define a complex cable harness. The 3D topology can be defined either from scratch or by loading an existing harness via a Nastran or STEP AP212-KBL import filter. Separate dialogs enable the definition of four basic types of cables: single wires, ribbon cables, twisted pairs and shielded cables (compact or braided shields). Any of these basic cable types can be defined and stored in a user defined library. A bundle dialog allows the convenient definition of exact or random cable cross-section. The transfer impedance of a braided shield can be directly defined or by using the built-in transfer impedance calculator extracting the impedance out of geometric characteristics of the shield.
Set-up or import arbitrary metallic 3D shapes from simple ground planes up to complex chassis structures. Moreover a powerful 3D full wave solver for the calculation of the electromagnetic field around the cable's environment is provided.
Equivalent circuits are generated out of the cable harness based on classical transmission line theory. The cable harness is automatically meshed along its extension and adequate segments where to calculate the transmission line parameter are created. Skin effect and dielectric loss is modeled for both frequency and time domain simulation. The equivalent circuits can be exported in several SPICE formats.
CST CABLE STUDIO® uses CST DESIGN STUDIO™ to define passive and active devices on the cable terminations with the help of an easy-to-use schematic. The powerful built-in network simulator inside CST DESIGN STUDIO™ enables the simulation of the whole system consisting of the equivalent circuit of the cable harness and its termination.
Data exchange of currents (on the cable) and electromagnetic fields (around the cable) between the circuit simulator and 3D full wave kernels. This enables the hybrid methods for simulating the effects of coupling fields into cables and the radiated fields from cables (uni- and bi-directional field coupling).
Fast and memory efficient FI-method.
Extremely good performance due to Perfect Boundary Approximation (PBA) and Thin Sheet Technique (TST) for solvers using hexahedral grids.
