Computer Simulation Technology (CST) has announced new features to automate workflows for field source coupling and multiphysics simulation using its System Assembly and Modeling (SAM) framework.

Since 2012, CST has offered the ability to link together multiple simulation and post-processing tasks using the SAM framework in its EM simulation software, CST STUDIO SUITE. The 2014 release of this software builds on this with features that automate the creation of SAM projects for common design tasks, such as antenna placement, emissions analysis and thermal detuning.

Multiphysics workflows, which combine full-wave EM simulation with thermal simulation, can now be created using the wizard from the schematic view in CST STUDIO SUITE. This means that all the solvers are set up and connected, and the entire simulation can be started with a single click. For simulations with temperature dependent materials, SAM allows simulations to be iterated until convergence is achieved. Mechanical simulations can be easily added to the workflow, allowing expansion and detuning effects to be calculated. All solvers are integrated in the same parametric 3D modelling GUI, making parameter studies and optimisation runs including EM-thermal couplings possible.

Field source coupling workflows can also be automated. This allows different components to be simulated with different solver types, with the fields calculated in one simulation used as the excitation in the next. These are useful for multiscale simulations, such as EMC in complex systems, installed performance of antennas on electrically large platforms, and small antennas
with large reflectors.
