A high fidelity parallel static structural analysis capability is created and interfaced to the multidisciplinary analysis package ENSAERO-MPI of Ames Research Center. This new module replaces ENSAERO's lower fidelity simple finite element and modal modules. Full aircraft structures may be more accurately modeled using the new finite element capability. Parallel computation is performed by breaking the full structure into multiple substructures. This approach is conceptually similar to ENSAERO's multizonal fluid analysis capability. The new substructure code is used to solve the structural finite element equations for each substructure in parallel. NASTRANKOSMIC is utilized as a front end for this code. Its full library of elements can be used to create an accurate and realistic aircraft model. It is used to create the stiffness matrices for each substructure. The new parallel code then uses an iterative preconditioned conjugate gradient method to solve the global structural equations for the substructure boundary nodes.Eldred, Lloyd B. and Guruswamy, Guru P.Ames Research CenterPARALLEL COMPUTERS; STRUCTURAL ANALYSIS; FINITE ELEMENT METHOD; STIFFNESS MATRIX; AIRCRAFT STRUCTURES; AIRCRAFT MODELS; COMPUTATION

The Greeks invented them. All manner of people in the European Middle Ages used them, often with creative and brilliant effect. Victorian schoolmasters in England almost buried them and the pupils who had to cram facts parrot-fashion. Originally published in 1972, this title brought mnemonics back into focus with a new collection designed for current use. A mnemonic is anything that gets your memory working. When in the month does the third quarter-day fall? What order have the planets from the sun? Are you sure about the kings and queens of England? People nowadays have so much to remember that even those quite happy with √2 = 1.414 may prefer to chant ‘I wish I know the root of two’ and remind themselves in that way. Although some entries are very much of their time, this title reminds us that mnemonics are still a useful tool in a world where technology means most people feel they have little need to remember.
