Faster Design Cycles with High Performance Hardware
In times of growing product complexity and shorter development cycles simulations are an essential part of a development process. These help the engineer to analyze a large number of variants of a design within a short time without building up prototypes for each design alternative. The computational time needed to complete a simulation with a certain accuracy level is a critical measure, which in the end decides the feasibility of the simulation. Much can be done to reduce the computational time, such as choosing an appropriate solver and solver settings which are well suited to the problem under study. However, many simulation tasks still require such a large amount of computational resources, e.g. because of extensive parameter studies, a high model complexity, or simply a large number of mesh cells needed for the discretization, that it is impractical or even impossible to handle them using a standard workstation computer. High Performance Computing (HPC) techniques help to bring down the computational time of such simulations or make the handling of complex models possible. This webinar gives an overview of the hardware based acceleration techniques offered by CST STUDIO SUITE. The supported systems range from single off-the-shelf workstations to high-end cluster based solutions. Typical application examples are discussed as well as the integration of CST STUDIO SUITE in HPC cluster systems.

New simulation workflows for predicting radiated emissions from electronics systems
The final webcast in the series will discuss powerful new workflows for reliably predicting radiated emissions from electronics systems. We start by importing a complex PCB model into CST PCB STUDIO and applying new EMC rules checking algorithms to rapidly identify potential weaknesses in the design. Critical nets, planes and vias are then analyzed to determine the differential mode (DM) to common mode (CM) conversion caused by driver skew and line imbalance. Finally, the resulting transient noise waveforms are injected into a 3D model of the connector/cable assembly and radiated emissions predicted. Important features of a typical anechoic chamber test are represented in the model using external ground plane reflections and cylindrical scanning to detect the peak emissions.

EMC/E3 analysis of rotorcraft electrical system exposed to antenna radiation and incident EMP
The first webcast in the series discusses the application of full wave modeling to predicting EMC/E3 performance in a rotorcraft. We start by investigating the coupling from a blade installed on the fuselage to internal cable systems. CST CABLE STUDIO is used to efficiently and accurately model the bi-directional interaction between electromagnetic fields and the complex cable system. True transient co-simulation enables direct time-domain analysis of voltages and currents induced in cable systems, due to an incident EMP. Finally, non-linear components are added to the model to assess the performance of transient protection devices (TPD’s).

Modeling the susceptibility of enclosures to ESD and the effect of attaching cables
The second webcast in the series discusses recent advances in modeling ESD generators using CST STUDIO. Direct transient analysis is used to simulate the ESD test waveforms defined by the IEC 61000-4-2 standard. We demonstrate the importance of modeling the physical geometry of the generator, including the ground strap. We simulate a direct contact discharge to an enclosure and predict the resulting current paths and radiated electromagnetic fields. Finally, we investigate the effect of attaching cables to the enclosure.

Simplifying the Workflow - benefits of the CST and Cadence Partnership
Cadence and CST offer very effective solutions for high speed PCB/package co-design. Two different workflows will be presented: 1) the “EDA centric” approach that allows the full wave simulation to be run as a fully background process with back annotation of the results to the layout environment and 2) the “EM centric approach” that focuses on the full wave environment. The benefits of such level of integration in the daily work of design engineers will be discussed.

Advanced system simulation for multi-channel MRI coils
Magnetic Resonance Imaging (MRI) has gained a lot in popularity in medical diagnoses over the past years thanks to the advantages it offers over other imaging techniques. The complex overlay of magnetic fields at frequencies from static to HF makes field simulation - even including circuit based tuning - an essential and integral part of the design and optimization process of the complete MRI system. CST STUDIO SUITE(tm), with its complete technology approach, is ideally suited to this task. Knowledge of the field distribution inside the body is crucial for the patient's safety. Since measurement of these internal fields is impossible, electromagnetic simulation can give the MRI system designer invaluable insight. Improved image quality can be achieved with the new generation of high-field MRIs, but the price of the related higher operating frequencies is that even more stringent technical challenges are introduced. These typically have to be addressed by using multi-channel coils. Using real-world examples, this webinar will give an overview of the complete MRI workflow including coil-design, circuit-based tuning, multi-channel optimization, and dedicated post-processing such as full system SAR and bio-heat evaluation.

BioEM simulations for improved medical diagnosis and treatment
Interaction of the human body with electromagnetic fields is widely used in medical devices for both diagnosis and therapeutic purposes. Over the last decades there has e.g. been a continuous trend to replace X-ray-based devices in favor of EM-based ones. Additionally, wireless communication of implanted devices is gaining importance. The main challenge during the development of such devices, is the detailed understanding of the field distribution inside the body, since measurement inside living organisms is almost impossible. Here, simulation can be of great benefit. In this webinar we show that human body models have evolved to the point where both the electromagnetic radiation effects as well as macroscopic effects, such as heating, Specific Absorption Rate (SAR) distribution, etc. can be predicted with tools provided by CST. Through the appropriate selection of a body model, it is possible to personalize medical treatment plans and greatly improve diagnosis tools without the need for excessive invasive testing. Using several examples, we will show the toolbox of features related to biomedical simulations which are available to the user of CST STUDIO SUITE. These include the calculation of field distributions inside and the power absorbed by the body and thermal effects due to these fields.

Simulation: Enabling In-flight Connectivity
Mobile phone and wi-fi communication while travelling by air is now being offered by several airlines and will become standard in future. Ensuring a reliable link depends on having properly designed antennas for the in-aircraft picocell base-stations and for the satellite or ground links outside the aircraft. Simulation is key for the optimal design of these antennas, and the selection of methods built in to CST STUDIO SUITE 2011 allows the engineer to use the best tool for each stage of the link.
