/> Researchers and engineers use CST STUDIO SUITE for the design of EM based components in application areas as diverse as MW&RF component design, EMC and signal integrity analysis. CST's latest software release, CST
STUDIO SUITE version 2011 and its multitude of powerful new features and functionality can help them to streamline their workflows and shorten development cycles.

Automatic optimization and sensitivity analysis are key requirements in a highly efficient design flow. Both of the CST MICROWAVE STUDIO (CST MWS) general purpose electromagnetic solvers - time and frequency domain - can provide sensitivity information for an arbitrary number of parameters in just one simulation run. The newly implemented trust region framework in CST STUDIO SUITE 2011 can employ the sensitivity information to cut down optimization time dramatically. Yield analysis for complex three dimensional models is now available at virtually no additional computational cost. High performance computing options are now also available for the frequency domain and the integral equation solver.

Engineers interested in the analysis of radiated emissions and susceptibility will benefit from a single unified environment for all EMC related modeling tasks, including greatly simplified model set up and simulation. The CST MWS TLM solver (CST MICROSTRIPES) and CST CABLE STUDIO (CST CS) provide powerful features for real world EMC analysis including coupled simulations which enable large system analysis and installed
performance studies. In pre-processing, the definition of compact equivalent aperture models and cable harnesses will be performed in CST's familiar design environment. Coupling between the electromagnetic field and cable solvers is further enhanced to enable direct transient simulation of susceptibility problems in systems containing complex cable bundles, including shielded twisted pair circuits.

The multiphysics flow inside CST STUDIO SUITE 2011 has been enhanced further. Based on one single simulation model, the simulation task concept facilitates optimization, considering electromagnetic, thermal and mechanical. The temperature calculated from the electromagnetic losses can be used to change the material parameters automatically for a consecutive electromagnetic field simulation. CST MPHYSICS STUDIO now also features a thermal solver on tetrahedral grids.
