CST highlights simulation and solver tools at IMS

Computer Simulation Technology (CST) announced several new capabilities at the IEEE MTT-S International Microwave Symposium in Boston this week. First, The company said it now offers flexible simulation acceleration options such as multi-CPU processing, GPU processing, cluster computing, and distributed computing to satisfy customer requirements. In order to protect customer investments as well as to facilitate the choice of the most effective acceleration solution for a given simulation model, CST has introduced a token scheme that enables the versatile access to as well as the combination of different simulation acceleration options.

“The reduction of simulation time is a continuous requirement in R&D departments,” commented Dr. Martin Timm, marketing director at CST. “Now customers can choose the appropriate acceleration flat-rate to access a flexible system capable of adapting to current and future acceleration requirements.”

The company also presented a new CST Microwave Studio solver module for electrically large structures; the module supports engineers working on applications such as antenna placement and radar cross-section simulation. The new module targets a range of simulation model sizes beyond 100 wavelengths. “Our customers appreciate our work exploring new regimes in electrical size. The introduction of our integral equation solver in 2006 fulfilled the needs of one customer segment, but we have noticed a strong tendency towards simulating even larger structures within our design environment,” stated Dr. Bernhard Wagner, managing director, sales and marketing, CST. “CST is responding to this demand with the introduction of the asymptotic solver, thus reinforcing our claim to offer complete technology for 3D EM simulation.” The asymptotic solver will be available in CST Studio Suite 2010, which is due for release in January 2010.

Also at IMS, CST announced that the CST Microwave Studio frequency domain solver will feature third-order and mixed elements with the 2010 release. In addition, with the introduction in version 2009 of the True Geometry Adaptation technique (which improves the geometrical representation of a structure during the mesh adaptation process), CST offers a technique that overcomes an inherent accuracy problem of traditional FEM codes, which refine the mesh but not the segmented geometry. Version 2010 will feature third-order elements alongside the already available first and second order elements. These will enable electrically larger problems to be solved, as the spatial sampling of the wave can be reduced and therefore the memory efficiency in homogenous regions increased. In addition, the combination of all three types of elements allows the efficient tackling of simulation models that feature a combination of electrically small, detail rich portions as well as larger homogenous areas.

“We are committed to supplying our customers with cutting edge simulation technology, allowing them to select the numerical method which is most appropriate for their current task,” commented Dr. Peter Thoma, managing director of R&D at CST. “This FEM implementation with 3rd order and mixed elements represents a major technological step in our frequency domain technology, opening the way to an even more diverse customer base.”
