  • Why create a MyCST Account ?

    A MyCST account may facilitate your access to many of the offerings on the CST website, for example the registration for eSeminars and the watching of eSeminars recordings, setting email preferences, and there is more functionality to come. It is required to participate in workshops and trainings.

  • Personal PreferencesAllows you to update your email preferences and areas of interest. It helps us to personalize your experience.

  • EventsSearch for events by location, industry and application. Once you are registered, you will be able to manage your registrations and check important details about your events. This section also provides you with a repository for Workshop & Training material.

  • LibraryYou can collect articles you find on the CST website to reference or read later by clicking on the “Add this article” button at the bottom of the article page.

  • Create Your Own Account
  • Need technical Support ?

    Customers can customize their accounts once they have completed the account creation process. This platform acts as vivid interface between CST and our customers.

    We therefore offer access to the latest Service Packs (including an automatic notification that a new Service Pack is available), a steadily growing database of Frequently Asked Questions (FAQs), Application Notes and Training Videos, as well as an individual FTP section for easy exchange of large files with our support team.

  • Do I need an Account?To access the Support Site a valid maintenance contract and a one-time registration is required.

    Please note that your Support login does not work for the MyCST account.

Solvers

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.
