CST Studio Suite 2015 SP4 Update Computer Simulation Technology AG (CST) has released an update for 2015 version of its flagship electromagnetic simulation software CST STUDIO SUITE, a package of tools for designing, simulating and optimizing electromagnetic systems, and is used in leading technology and engineering companies around the world. The three pillars of CST’s products are accuracy, speed and usability. CST STUDIO SUITE is used by engineers and researchers working across the electromagnetic spectrum to model systems and optimize designs. Its tightly-integrated solvers cover a broad range of frequencies and geometrical scales, and are complemented by more specialized technology for applications such as PCBs, cables, thermal analysis, and charged particle devices. As devices become more compact and more connected, the old distinctions between different fields of engineering break down. Increasingly, even a single design task can involve multiple simulation disciplines. With CST STUDIO SUITE 2015, the links between the different simulation domains have been tightened and new tools have been added to allow users to go beyond what can be done with electromagnetic field simulation alone. Synthesis and design tools supplement simulation by making it possible to generate initial designs quickly and accurately. To help antenna engineers get the most out of simulation, CST has recently added Filter Designer 2D, and is introducing the new Phased Array Wizard. These new tools complement the antenna synthesis capability of Antenna Magus and speed up the whole EM design process The solvers themselves are now also more powerful and more flexible. The frequency domain solver has had several performance improvements to boost its power and versatility, making it much easier to simulate extremely large and complex multiport models such as multi-pin connectors or densely populated antenna arrays. The introduction of nearfield sources to the frequency domain solver and the asymptotic solver mean that these solvers can now be linked more easily to simulations using other solver types. Users working at the limits of current computing technology will also benefit from the new high-performance computing features in CST STUDIO SUITE 2015. The ability to access high-performance storage on computer clusters makes the simulation of very large models, which can generate many gigabytes of field data, much more efficient, and the new Intel Xeon Phi co-processor is supported, increasing the range of hardware acceleration options for users.
