Upgraded Simulation Toolset for Electromagnetics Ships

Computer Simulation Technology AG (CST; Darmstadt, Germany, and Framingham, MA) has announced that it is now shipping the newest version of its flagship product for EM (electromagnetic) simulation, CST STUDIO SUITE 2013. CST STUDIO SUITE encompasses a range of integrated EM simulation tools, including the high-frequency package CST MICROWAVE STUDIO (CST MWS) and CST PCB STUDIO (CST PCBS) for simulating signal integrity and EMC/EMI EMI on printed circuit boards. Key new features provided in CST STUDIO SUITE 2013 include a new ribbon interface, enhanced performance, and new analysis tools, according to the company.

CST STUDIO SUITE is made up of six modules that form an integrated design environment providing an array of technologies and capabilities for electromagnetic design across a wide range of frequencies — static to optical. Analyses can include thermal and mechanical effects as well as circuit simulation. With version 2013, the company highlights changes to its CST MICROWAVE STUDIO module as well as general changes that span across the entire suite.

CST says that version 2013’s new ribbon-based user interface focuses on the simulation workflow to help lead the engineer from set-up and modeling to simulation and post-processing. Other new features, such as a Project Wizard and QuickStart Guide, augment the ribbon interface and make preparing and configuring new projects straightforward, the company says.

Beyond the ribbon-based user interface, general enhancements incorporated in CST STUDIO 2013 include automatic storage of parametric results and cylinder scans for farfields of all solvers. The company adds that, through collaboration with Intel, its solver code has been optimized to boost performance when the software is run on Intel’s latest generation of processors.

CST MICROWAVE STUDIO (CST MWS) provides time and frequency domain solvers for 3D simulations of high frequency devices such as antennas, filters, couplers, and planar and multi-layer structures. The company reports a number of changes to the application’s transient and frequency domain solvers as well as its asymptotic solver.

Enhancements to the CST MWS transient solver include more memory-efficient mesh generation than with previous versions; nonlinear, frequency-dependent materials, such as Kerr and Raman materials; the ability to handle more than 2 billion mesh cells; and GPU (graphics processing unit) acceleration for the TLM (transmission-line matrix) solver.

Curved tetrahedrons are now the default with the CST MWS frequency domain solvers, and the Eigen mode solver now supports lossy dielectrics. Other improvements over previous versions of the application are reported in such areas as mesh set-up, performance, and memory efficiency. The CST MWS asymptotic solver now offers range profiles and sinograms for RCS (radar cross section).

The company also reports improvements to its CST DESIGN STUDIO (CST DS) for 3D EM/circuit co-simulation and synthesis as well as its CST PARTICLE STUDIO (CST PS) for simulating free moving charged particles. The former is said to offer improved automation for model set-up and result creation while CST PS now provides GPU support for particle-in-cell simulations.

Other modules in the CST STUDIO SUITE include CST EM STUDIO for designing and analyzing static and low-frequency EM applications; CST CABLE STUDIO for simulating signal integrity and performing EMC/EMI analyses of cable harnesses; CST PCB STUDIO for simulating the signal integrity and EMC/EMI EMI properties of printed circuit boards; and CST MPHYSICS STUDIO for thermal and mechanical stress analysis.
