High-Performance Algorithms for Analysis and Design

- Structural Mechanics, Electromagnetics & Acoustics -

NASA's General-Purpose Solver (GPS) is a rapid matrix equation solver for large-scale structural, electromagnetic and acoustic analyses (8.3 million complex equations). GPS minimizes solution time and memory by exploiting matrix properties (sparse/dense, real/complex, symmetric), computers (sequential/parallel, from Supercomputers/Unix to PCs/Windows or Linux) and languages (FORTRAN, C++, and Java for Web use). Numerous production codes (e.g. Livermore Labs Nike-3D, NASTRAN: MI & NE, STAGS, ALGOR, GD/Electric Boat, Solversoft, UIUC Warp3D…) exploit the NASA solver. User feedback and an Internet Challenge (comparing GPS with other solvers for NASA benchmarks) are solicited by NASA.

EIGr, a fast NASA eigensolver, calculates vibration modes and frequencies. EIGr reduced the time to calculate the first 100 vibration modes for the 5,156 equation Next Generation Space Telescope (NGST) model from 45.6 minutes to 31 seconds (88X speedup) opening the door for trade studies on more refined and accurate NGST models.
