  • 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.

CST – Computer Simulation Technology

System Assembly and Modeling

 

Complete Technology for EM simulation is one of the key strengths of CST Studio Suite®. Having access to a choice of available simulation methods allows the user to select the optimal solver for the simulation of a given component. CST Studio Suite takes simulation a step further: System Assembly and Modeling (SAM) provides an environment that simplifies the management of simulation projects in many ways.

A device may consist of more than one component, each of which may require a different solution method for optimal simulation performance. The performance of such a large or complex system might be affected by interaction between components, so an optimization of the individual components might not be sufficient. An optimization of the entire system may be required. SAM provides a framework for addressing this requirement.

In SAM a system is described by a schematic. In the simplest case this is one block representing a parameterized 3D model. The user defines the evaluations for this model by setting up simulation tasks. SAM helps you to compare the results of different solvers or model configurations within one simulation project. The user can also set up a linked sequence of solver runs. For example, the electromagnetic analysis of a filter could be followed by a thermal simulation, then the filter’s resulting mechanical deformation could be determined, and finally this geometric change could be used in another electromagnetic simulation to investigate the detuning effect. All simulations and links can be defined easily in SAM to enable a seamless multiphysics work flow.

By adding other models to the schematic, the user can create a 3D system. SAM helps the user to define the geometric alignment of the various components. Simulation tasks can be defined that include single or multiple components and the user can specify which components should be simulated in 3D, and which solver and CST simulation acceleration options should be used for those simulations. Components could also be represented simply by their S-parameter behavior or by an equivalent field source in the system simulation. This combination of different levels of simulation helps to reduce the computational effort required to analyze a complex model accurately. If required, SAM naturally also enables the user to create and simulate their system in full 3D.
