CST® STUDIO SUITE® is an electro-magnetic simulation tool used to de-sign, analyze and optimize devices and

systems at all stages of the development pro-cess. It is used in industries as diverse as elec-tronics, automotive, aerospace, medical and energy, and covers the electromagnetic spec-trum from statics to optics. By replacing physi-cal prototypes with virtual ones, engineers can

study how their products work at the earliest stages of design and reduce the number of physical models that need to be constructed.

For virtual prototyping to be a viable op-tion, the simulation tools need to be accurate without sacrificing performance. For this rea-son, the release of CST STUDIO SUITE 2016 builds on the success of previous versions with a range of new features that make the analysis of systems more powerful while building on CST’s reputation for accuracy.

CHARACTERISTIC MODE ANALYSISCharacteristic Mode Analysis (CMA) is a

technique developed to provide physical in-sight into the behavior of a conducting surface by calculating the current-modes that it can support. For example, CMA can be used on a patch antenna to identify the resonant fre-quencies of the patch. This allows engineers to tune the antenna to the correct frequen-cies and determine where to place the feed to couple into a particular radiating mode. Fig-ure 1 demonstrates one typical application of CMA to calculate the modes on a GSM-900 PIFA antenna.

ProductFeaturethe previous mesh to fit the new struc-ture. This speeds up the meshing pro-cess, and can also improve accuracy by reducing the noise associated with repeated mesh generation.

A range of other improvements to the mesh engines include more intel-ligent mesh adaptation, sliding mesh-es for moving part simulation, and the ability to define mesh-independent parameters.

HIGH-PERFORMANCE COMPUTING

For very large or complex simula-tions that approach the limits of con-ventional computing hardware, high-performance computing (HPC) can offer significant time advantages. CST STUDIO SUITE supports multi-threading and multi-CPU paralleliza-tion in shared memory environments, hardware acceleration (Nvidia® Tes-la® GPU and Intel® Xeon Phi®), and cluster computing using distributed computing and MPI.

It was recently certified as Intel®

Cluster Ready, and its cluster comput-ing capabilities have been expanded with the ability to perform True-Tran-sient EM/Circuit Co-Simulation on MPI clusters. In addition, the Asymp-totic Solver now also supports GPU acceleration, which can significantly speed up bistatic radar simulations and other simulations with large num-bers of observation points.

LINUXCST has supported Linux in HPC

compute cluster environments for many years. This allowed simulation jobs to run in batch mode without user interaction. However, Linux-based operating systems are now becoming increasingly common for workstations, and CST STUDIO SUITE 2016 can now be used interactively directly on a Linux machine. This includes the pow-erful 3D modeling tools and results viewer, greatly increasing the number of tasks that can be performed entirely in a Linux environment.

behavior of electronic systems affect-ed by pulses or realistic digital signals.

IMPROVED MESHINGThe accuracy and performance of

a simulation are heavily dependent on the quality of the mesh which de-scribes the structure. Achieving very high mesh quality has previously led to innovations including PERFECT BOUNDARY APPROXIMATION (PBA)® for hexahedral meshes, True Geometry Approximation for curved tetrahedral meshes, and intelligent mesh engines for more efficient dis-cretization. Two important new fea-tures have now been added to the repertoire: hybrid curved surface meshing and moving mesh optimiza-tion. The surface mesh used by the In-tegral Equation Solver is very efficient for structures such as reflector an-tennas and vehicle bodies, which are constructed from large, thin sheets of metal.

With the new version, the surface mesh can now use a hybrid combina-tion of triangular and quadrilateral mesh cells, and these polygons can be curved and conformal to the struc-ture (see Figure 2). This means that a structure can be discretized very ac-curately with fewer mesh cells com-pared to traditional meshes, which can accelerate simulation significantly.

Moving mesh optimization is most useful when designing and tuning highly sensitive structures such as fil-ters, which are usually described us-ing a tetrahedral mesh. At each step of an optimization of such a structure, the model geometry changes slightly, which means that the mesh needs to change as well. Instead of recalculat-ing the mesh from scratch, CST STU-DIO SUITE 2016 can instead adjust

The CMA tool is integrated into the method-of-moments (MOM) Inte-gral Equation Solver in CST STUDIO SUITE, and calculates the modal sig-nificance (a measure of which modes are dominant at a particular frequen-cy), far field radiation pattern and sur-face current distribution associated with each mode, with automatic mode-tracking. These features are particular-ly useful for analyzing and optimizing printed antennas, which often have to be compact and multiband.

REPRESENTING REALITYTo be useful to engineers, a simu-

lation needs to accurately represent the physical system. CST STUDIO SUITE offers an extensive library of material types, such as lossy met-als, ferrites and nonlinear materials. The 2016 version adds new advanced types, including arbitrary graded ma-terials and perforated materials. Mea-sured or simulated data can now be used to generate realistic thin panel materials to be included in models. This is particularly useful for model-ing composite materials, such as car-bon fiber, which have complex elec-tromagnetic properties due to their structure.

Nonlinear circuit elements can be integrated directly into 3D EM simulations through CST’s True Tran-sient EM/Circuit Co-Simulation. In CST STUDIO SUITE 2016, the link between circuit and EM simulation is strengthened further by the new Combine Results in Transient Task feature. This allows the results of a 3D simulation to be included in a tran-sient circuit simulation with no post-processing required. This is a feature that will benefit EMC engineers, for example, who need to simulate the
