Software Tool Enables High-Fidelity Simulation of Explosive Device Effects

High-fidelity simulation tools are used as an acceptable surrogate for real-world tests. These tools accelerate development and reduce cost, while informing weapons development and systems survivability for defense and homeland security applications. As weapons grew in complexity, analytical methods became insufficient and high-fidelity computational methods became necessary.

Embedded Switch Fabrics

Mercury Systems, Inc. (Chelmsford, MA) has announced its Micro Via Radial Interconnect (MVRI) technology. MVRI improves OpenVPX™ switch fabric interconnect data rates by increasing the signal integrity margin approximately three-fold, enabling switch fabrics and point-to-point connections to run faster and more reliably. MVRI technology is scalable, enabling it to support signaling rates greater than 14 wGbaud per channel. Planned future fabric implementations, using InfiniBand enhanced data rate (EDR) or 100Gb Ethernet, especially benefit from the performance boost MVRI technology delivers. Intel® Xeon® server-class OpenVPX ecosystems in combination with the latest InfiniBand and Ethernet switch fabrics provide the embedded processing capability needed for challenging electronic warfare (EW) and C4ISR processing applications.
