CST automates EM and multiphysics simulation workflows

June 4, 2014

Computer Simulation Technology (CST) announces new features to automate workflows for field source coupling and multiphysics simulation using its System Assembly and Modeling (SAM) framework at MTT-S IMS, booth # 1423.

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 CST STUDIO SUITE 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 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. These allow 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.

“System Assembly and Modeling is CST’s most powerful tool for system-level simulation, and is one of the unique selling points of our software,” commented Dr. Ulrich Becker, Director Engineering & Support, CST. “At IMS, we hope to show our users how they can make their simulation workflows more efficient and more versatile using SAM.”

New and improved features for SAM, including the antenna placement workflow and the automatic creation of 3D models from circuits, will be demonstrated on June 3rd and 4th at the CST booth, #1423, at MTT-IMS 2014.
