Development of Automated Structural Health Monitoring and QualificationMethods and Software for Composite Overwrapped Pressure VesselsMSC-25421-1NASA has integrated industry-standard and new, novel analysis methods for assessing the structural healthof composite overwrapped pressure vessels (COPV). By significantly increasing throughput, the software hasthe ability to provide real-time assessments. Adaptive analysis methods have been incorporated into the technologyto provide modal analyses at specified points of a structure’s life (e.g. loading, unloading, and dwells),thereby increasing the tool’s utility and ease of use for acoustic emission testing.U.S. Government Purpose ReleaseFan Broadband Noise Prediction CodeLEW-17279This NASA-developed technology predicts the dipole and quadruple noise that results from the interactionof anisotropic homogeneous turbulence with a rotor or stator.U.S. Release OnlyFast Scattering Code (FSC), Versions 3.1 and 3.2LAR-17828-1The Fast Scattering Code (FSC) is a computer program designed to predict the scattered acoustic fieldthat results from the interaction between a known incident sound and arbitrary three-dimensional surfacesimmersed in a potential background flow. The technology is based on the equations of time-harmonic,linearized acoustics and employs equivalent sources for solving an exterior Helmholtz equation boundaryvalue problem (BVP). The incident sound can be generated by the FSC using a collection of simplepoint multipoles (monopoles and dipoles), or it can be provided by the user from other prediction codes.Predictions for high-frequency/large scale-combinations yield linear systems with millions of unknownsand memory requirements beyond the capabilities of most advanced computer systems to date. Thecomputational engine of the FSC has been totally redesigned to alleviate the frequency limitations of thecode by employing numerical algorithms that drastically reduce computer resource utilization and takeadvantage of multiprocessor platforms.U.S. Release OnlyFATMaCC Five-Axis, Three-Magnetic-Bearing Control CodeLEW-17293This code achieves full rotor levitation and control at a loop time of 50 microseconds. It will control a fiveaxissystem in either a centralized or decentralized mode at a loop time of 56 microseconds.U.S. Release OnlyGeophysical Finite Element Simulation Tool (GeoFEST)GSC-14846-1Consisting of approximately 7,000 lines of C source code, GeoFEST is a two- and three-dimensional finiteelement package for modeling solid stress and strain in geophysical and other continuum domain applications.The software runs on diverse UNIX derivatives, including Linux, HPUX, and SunOS. GeoFEST isdescended from an earlier-generation Fortran code running under VAX VMS (VISELAS) and an earlier UNIXC code (VISCO).U.S. Government Purpose Release4. System TestingGeophysical Finite Element Simulation Tool (GeoFEST), Version 4.3(P)GSC-14847-1Consisting of approximately 11,000 lines of C source code, GeoFEST (Version 4.3P) is a two- and threedimensionalfinite element package for modeling solid stress and strain in geophysical and other continuumdomain applications. The software runs on diverse UNIX derivatives, including Linux, HPUX, and SunOS.GeoFEST’s computational engine employs Crout factorization for the direct inversion of the finite elementmatrices (as well as conjugate gradient for an iterative solution option). Data formats can be adapted toaccommodate visualization and graphically oriented input/output. Physics models supported by the codeinclude isotropic linear elasticity and both Newtonian and power-law viscoelasticity via implicit/explicitquasi-static time stepping. In addition to triangular, quadrilateral, tetrahedral, and hexahedral continuumelements, GeoFEST supports split-node faulting, body forces, and surface tractions.U.S. Government Purpose Release32NASA Technology Transfer Program Software Catalog 2014
