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.
