NASTRAN is a structural calculation program that applies the finite element method (FEM). It was initially developed by NASA[1] in the late 1960s with funding from the US government for the aerospace industry. The MacNeal-Schwendler Corporation, MSC Software"), was one of the main developers of the NASTRAN code, which was initially open source in the public domain.[2][3][4].
Nastran is written in Fortran and its code consists of more than a million lines.
Nastran was widely used in the aerospace industry until the turn of the century.
History
The 1964 annual review of NASA's structural dynamics research program revealed that research centers were separately developing structural analysis software that was specific to their own needs. The review recommended that a single generic software program be used instead. In response, an ad hoc committee was formed, which determined that no existing software could meet their requirements. They suggested establishing a cooperative project to develop this software and created a specification that described its capabilities.
A contract was awarded to Computer Sciences Corporation (CSC) to develop the software. The first name used for the program during its development in the 1960s was GPSA, an acronym for General Purpose Structural Analysis. The eventual NASA-approved formal name for the program, NASTRAN, is an acronym formed from NA SA STRucture ANalysis. The NASTRAN system was released to NASA in 1968. In the late 1960s, MacNeal-Schwendler Corporation (MSC) began marketing and supporting its own version of NASTRAN, called MSC/NASTRAN (which eventually became MSC Nastran). The original software architecture was developed by Joe Mule (NASA) and Gerald Sandler (NASA), and Stephen Burns (University of Rochester).
The NASTRAN software application was written to help design more efficient space vehicles, such as the space shuttle. NASTRAN was released to the public in 1971 by NASA's Technology Utilization Office. Commercial use of NASTRAN has helped analyze the behavior of elastic structures of any size, shape or purpose. For example, the automotive industry uses the program to design front suspension systems and steering linkages. It is also used in the design of railways and automobiles, bridges, power plants, skyscrapers and airplanes. The program alone was estimated to yield $701 million in cost savings from 1971 to 1984. NASTRAN was inducted into the U.S. Space Foundation's Space Technology Hall of Fame in 1988, one of the first technologies to receive this prestigious honor.

The NASTRAN program has evolved into many versions. Each new version contains improvements in analysis capacity and numerical performance. Today, NASTRAN is widely used around the world in the aerospace, automotive and maritime industries. It has been claimed to be the industry standard for basic types of aerospace structure analysis, for example, linear, elastic, static and dynamic analyses.
In 2001, NASA released the NASTRAN source code with the "NASA Classics" package.[5].
In November 2002, MSC Software reached a final agreement with the Federal Trade Commission (FTC) to resolve an antitrust case against the company in connection with two acquisitions of rival CAE vendors, Universal Analytics, Inc. (UAI) and Computerized Structural Analysis & Research Corp. (CSAR). The FTC had alleged that the acquisitions represented anticompetitive activities. Under the terms of the agreement, MSC disposed of a cloned copy of its current Nastran software. The sale was made through non-exclusive, perpetual, royalty-free licenses to UGS Corporation. The latter was acquired by Siemens in 2007.
Currently, several vendors offer commercial versions of NASTRAN.

Contenido
NASTRAN es principalmente un solucionador para el análisis de elementos finitos; no tiene funcionalidad que permita construir gráficamente un modelo o mallar, y toda la entrada y salida del programa está en forma de archivos de texto. Sin embargo, varios proveedores de software comercializan pre- y posprocesadores diseñados para simplificar la construcción de un modelo de elementos finitos y el análisis de los resultados. Estas herramientas de software incluyen funcionalidad para importar y simplificar geometría CAD, mallar con elementos finitos y aplicar cargas y restricciones. Las herramientas permiten al usuario enviar un análisis a NASTRAN, importar los resultados y mostrarlos gráficamente. Además de las capacidades de procesamiento previo y posterior, varios proveedores de Nastran han integrado capacidades no lineales más avanzadas en sus productos Nastran.
Están disponibles las siguientes alternativas de software, todas ellas basadas en el código fuente original de NASTRAN:.
MSC Nastran
MSC Nastran is the original commercial Nastran product started by Dr. Richard MacNeal and Robert Schwendler in 1963. It is commonly used to perform structural analysis. Although it is used in all industries, it maintains a large number of users in the aerospace and automotive industries to perform computational stress and strain analysis of structure models at the component and system level. Since 1963, it has continued to evolve and expand its capabilities to dynamic, rotordynamic, nonlinear, thermal, high impact, NVH, fluid structural interactive, and fatigue analysis. Currently, it is combined with MSC Marc and LS-Dyna to provide highly non-linear coupled analysis solutions.
NASTRAN-xMG
Built from the same code base as the original NASTRAN software created by NASA including the original NASTRAN architecture and DMAP language, NASTRAN-xMG provides unlimited problem size, high-speed resolution technology, and substructure analysis options.
Nei Nastran
NEi Nastran is a general-purpose finite element analysis solver used to analyze linear and nonlinear stresses, dynamics and heat transfer characteristics of mechanical structures and components. It is available on a variety of platforms, including 32/64-bit Windows and Linux. This software was acquired by Autodesk in May 2014.
Simcenter Nastran
Previously known as NX Nastran. NX Nastran resulted from a US Federal Trade Commission action against MSC Corporation for alleged antitrust activity.[6] The antitrust settlement allowed for the purchase in 2003 of a perpetual royalty-free license to the MSC.Nastran 2001 source code by UGS. UGS was formerly the Unigraphics division of EDS. Nastran's CAE capabilities were added to NX Unigraphics CAD and other components to form the EDS/UGS PLM Solutions product lifecycle management suite. This product line was acquired by Siemens in 2007 and became Siemens Digital Industry Software.
The purchase included a perpetual, worldwide, non-exclusive license to the MSC.Nastran v2001 software program, other assets related to the software, and all copyrights and trademarks acquired as a result of MSC's acquisitions of Universal Analytics Inc. and Computerized Structural Analysis & Research Corp. in 1999.
Simcenter Nastran (NX Nastran) is now part of Siemens Digital Industry Software's Simcenter product portfolio as one of the main solvers within its Simcenter 3D CAE application.
OCF Nastran
Both source and binary copies of Nastran are available from the Open Channel Foundation for an annual license fee. This was part of the distribution of NASA's COSMIC Collection from the National Technology Transfer Center. It was published in June 2015 on GitHub.
Competence
There are currently numerous MEF products commercially available; some of them can read the NASTRAN input format although they do not carry the NASTRAN name.
