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) solver uses the 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 solver is 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.
