CST EMC STUDIO

The solvers included in CST EMC STUDIO have been selected to allow a wide range of

EMC workflows to be carried out in a straight forward way.

The transmission line matrix (TLM) solveris time domain method which is

especially well suited to EMC simulation. The TLM solver can use octree gridding

to significantly reduce simulation time on extremely complex structures, and

also supports analytic compact model representations of fine details.

The transient solver, based on the finite integration technique (FIT), is a general

purpose time domain solver and is best suited to broadband simulations of

radiated emissions and susceptibility.

The frequency domain solveris based on the finite element method (FEM), and is

often used to simulate conducted emissions. The frequency domain solver

includes a special meshing engine optimized for PCBs, which allows complex

boards to be simulated faster than conventional methods.

The cable harness solver is a specialized solver for simulating cables in complex

environments. There is a bidirectional coupling between the cable harness solver

and the time domain solvers, allowing cable harnesses to be integrated into a

3D model and analyzed using bidirectional simulation.

CST DESIGN STUDIO™ supplements the 3D solvers with circuit simulation. Non-linear

circuit elements can be included in a 3D simulation using true transient/circuit co-

simulation. CST DESIGN STUDIO also allows models to be linked together

through System Assembly and Modeling (SAM), making it possible to carry out hybrid

simulations of systems built up of individual components.

In addition, CST EMC STUDIO also includes the EMC rule checker from CST

BOARDCHECK™. This can quickly analyze imported PCB layouts against a set of design

rules, and highlight violations that may lead to EMC issues.
