A line of CAE software now includes CTH, a shock wave physics software that simulates high-speed impact and penetration, and Xpatch, an electromagnetics radar simulation software suite capable of predicting and analyzing high-frequency signatures. This government off-the-shelf (GOTS) application software suite is available on the manufacturer’s Altix and Silicon Graphics Prism family of servers, clusters, and visualization system. The Altix and Silicon Graphics Prism family of systems combines the HPC technologies of the Intel Itanium 2 processors, the open-source 64-bit Linux operating system, and NUMAflex scalable system architecture. The systems are designed to meet the needs of CAE simulation environments for advanced Department of Defense weapons development. Developed by Sandia National Laboratories, CTH software can be used to study weapon effects, armor/anti-armor interactions, warhead design, high-explosive initiation physics, and weapon safety considerations. This release of CTH v7.0 includes performance enhancements from code optimizations invoked with the Intel compiler and the Message Passing Toolkit (MPT), which provides industry-standard message-passing libraries optimized for systems running Linux. These libraries allow engineers to use standard, portable interfaces for developing parallel applications software while obtaining the best possible communications performance. Xpatch, developed by Science Applications International Corporation (SAIC), is a set of prediction and analysis tools that use the shooting-and-bouncing ray (SBR) method to predict realistic far-field and near-field radar signatures for 3D target models. The Xpatch toolset is used by the U.S. Air Force Research Laboratory and Defense Advanced Research Projects Agency (DARPA) for multiple radar simulation programs. Xpatch can be used to produce and analyze scattering data for realistic aircraft, missiles, ships, spacecraft, and ground vehicles.
