Nastran
Nastran (short for Na sa Str uctural An alysis system ) is on the finite element method (FEM) based solver without the possibility of graphical interaction and is usually along with pre / post processors allow users to create the calculation models, used.
description
The input files are pure text files and can therefore be easily exchanged between different pre- / post-processors and operating systems. Nastran was the first commercial FEM solver and due to its long history and the associated maturation, Nastran is considered the de facto standard for finite element calculations in the aerospace industry.
history
The development of this software began in the 1960s by the US space agency NASA at several locations with a view to opening up the universe. This turned out to be ineffective and therefore in 1964 the CSC company was commissioned to develop a uniform FEM solver. The name originally chosen was GPSA (General Purpose Structural Analysis) but was changed to Nastran by NASA. The software was initially written in Fortran and is characterized by an open architecture with the option of integrating your own routines. The source code was acquired by several software companies and continuously developed over the decades. The MacNeal-Schwendler Corporation (today MSC Software ) was of particular importance .
Commercial use began in 1971 and the first customer in Germany was Daimler-Benz in 1972 . Nastran was widely used early on in the aerospace and automotive industries. Due to the drop in hardware prices, the software was increasingly used in other industrial areas and at universities. Today Nastran is one of the most widely used FEM solvers.
In 1988, Nastran was inducted into the Space Technology Hall of Fame for outstanding service.
Versions
In the 1980s and 1990s, in addition to MSC Nastran, other derivatives (UAI-Nastran, CSAR-Nastran) were also represented on the market. Due to the acquisition of these competitors, MSC Software had created a monopoly and in 2002 was obliged by the US FTC to make Nastran available to competitors. Source code, documentation and the rights to permanent, license-free use were acquired from what was then UGS , now Siemens PLM . UGS released NX Nastran 1.0 in 2003. The best-known Nastran versions today are MSC Nastran, NX Nastran and NEi Nastran.
