What Does Performance Really Mean?

Product design cycles are tight, and there are many hurdles to be crossed between the concept and the final product. Simulation offers benefits throughout the design process, but to stay at the cutting edge, engineers, designers and researchers need their simulation results fast while still maintaining excellent accuracy. Performance is a combination of these two factors – speed and accuracy.

To make CST STUDIO SUITE® as useful as possible, we devote a substantial amount of development time to improving the performance of our products and optimizing the solver technology. Thanks to our co-operation with Intel®, our products can take full advantage of the power and speed of the latest generation processors. For more information about this, please see the Intel/CST solution profile.

Innovations such as the Perfect Boundary Approximation (PBA)®, the Thin Sheet Technique (TST)™  and True Geometry Adaptation enhance the efficiency of our flagship time domain and frequency solvers by improving their accuracy without compromising on speed. For models that are difficult to solve with these solvers, CST also have a range of other technologies which offer excellent performance for certain types of simulation. The asymptotic and integral equation solvers for example offer a practical approach for solving electrically large problems, such as antenna placement and RCS. High-Q structures, which are hard to simulate in the time domain because of how long they keep ringing, are much more efficiently calculated with the fast resonant solver.

Performance is not just about raw power, however. Usability also plays a key role in helping users achieve their goals, by streamlining the simulation workflow and allowing it to slot more easily into the product design process. To that end, we also work to ensure that CST STUDIO SUITE is very user-friendly. The Ribbon-based user interface guides the user through the simulation process, and the Project Wizard tool suggests the most suitable configuration and solver type for a fast, accurate simulation.

These three elements together – speed, accuracy and usability – are the basis of an effective workflow.  Only when all three are available, without compromise, can a simulation be called high performance.
