By employing the sensitivity information provided by both of the general purpose electromagnetic solvers of CST MWS-time and frequency domain-the number of 3D simulations and, therefore, the optimization time can be cut down dramatically. The newly implemented trust region framework uses parametric models to find optimal solutions for the given goals, without rerunning expensive 3D simulations. Hence, yield analysis for complex three dimensional (3D) models is available at virtually no additional computational cost. Further evaluations for different model parameter sets can be derived without restarting the full-wave simulation. In version 2011, sensitivity analysis can evaluate the S-parameter dependencies on various model parameters on the basis of this single broadband simulation.

Sensitivity and Yield analysisД¬ST MWS transient solver provides efficient computation of broadband S-parameters and field results in one single simulation run. The asymptotic solver benefits from the inclusion of surface impedance models for the simulation of coatings or seawater. This enables the simulation of arbitrarily polarized incident waves from different directions. CST MWS 2011 also allows the importing of more than one farfield source, thus enabling the computation of the coupling between several antennas, or of the combined farfield of multiple antennas.ДЇor radar scattering simulations, the structure can be simultaneously illuminated by multiple sources, the properties of which can be set by means of an excitation list. This makes the calculation of an installed antennaвЂ™s farfield possible, even for an electrically very large structure, such as the ship shown in Figure 3. These farfields can be computed by other CST MWS solvers including the transient or frequency domain solvers.

CST MWS features an integral equation solver using the multilevel fast multipole method (MLFMM) for structure sizes of up to about 1,000 wavelengths and an asymptotic solver based on the shooting bouncing ray method for even larger structures. HPC can greatly benefit the simulation of very complex structures, like the one shown in Figure 2, but switching from standard volume methods such as FIT or FEM to surface-based integral equation or ray tracing methods is often the more efficient approach for electrically very large structures.

The higher order curved elements will also be available for the CST MWS eigenmode solver and the fast resonant solver. These actually improve the representation of the input model continuously, rather than simply refining the first discretization of the model. In comparison to using simpler curvilinear elements (first order curved elements), which often suffer from the creation of inaccuracies in the mesh representation, higher order curved elements deliver a much smoother representation of arbitrary surfaces.ДЄs with all mesh adaptation schemes, simulations will only converge to the correct results if mechanisms such as True Geometry Adaptation are used. With version 2011, the CST MICROWAVE STUDIO (CST MWS) frequency domain solver will feature curved tetrahedral mesh elements of high geometrical orders.
