Nx Nastran User Guide
This paper is intended for NX Nastran users interested in exploring nonlinear solutions for their structural. From the Basic Nonlinear Analysis User's Guide. The NX™ Nastran® Aeroelasticity software solution enables you to analyze models in which structures are immersed in fluid flows, which as a result effect the stiffness of the structure itself. Aeroelasticity in general considers inertial, elastic and aerodynamic forces acting on a structure.
Contents. History The 1964 annual review of 's structural dynamics research program revealed that the research centers were separately developing software that was specific to their own needs. The review recommended that a single generic software program should be used instead. In response, an ad hoc committee was formed. The committee determined that no existing software could meet their requirements. They suggested establishing a cooperative project to develop this software and created a specification that outlined the capabilities for the software. A contract was awarded to (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 formal name approved by NASA for the program, NASTRAN, is an acronym formed from NASA STRucture ANalysis. The NASTRAN system was released to NASA in 1968.
In the late 1960s, the (MSC) started to market and support 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).
NX Nastran is a premier finite element method (FEM) solver for computational performance, accuracy, reliability and scalability. NX Nastran includes powerful solutions for linear and nonlinear structural analysis, dynamic response, acoustics, rotor dynamics, aeroelasticity, thermal analysis, and optimization.
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 Office of Technology Utilization.
The commercial use of NASTRAN has helped to 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 designing railroad tracks and cars, bridges, power plants, skyscrapers, and aircraft. The program alone was estimated to have returned $701 million in cost savings from 1971 to 1984. NASTRAN was inducted into the U.S.
Space Foundation’s in 1988, one of the first technologies to receive this prestigious honor. The NASTRAN program has evolved over many versions.
Each new version contains enhancements in analysis capability and numerical performance. Today, NASTRAN is widely used throughout the world in the aerospace, automotive and maritime industries. It has been claimed that NASTRAN is the industry standard for basic types of analysis for aerospace structures, e.g.

Linear elastic static and dynamic analyses. In 2001 the NASA released with the 'NASA Classics' package also the NASTRAN to the public via for fees.
In November 2002 reached a final agreement with the 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. The FTC had alleged the acquisitions represented anticompetitive activities. Under the terms of the settlement, MSC divested a clone copy of its current Nastran software. The divestiture was through royalty-free, perpetual, non-exclusive licenses to. UGS Corporation was acquired by Siemens in 2007. Commercial versions of NASTRAN are currently available from (MSC Nastran)and (NX Nastran).
Siemens AG purchased the former UGS Corporation from private equity concerns and their rights to the commercial version of NX NASTRAN in 2006. Autodesk purchased NEi Software in May 2014. Software architecture NASTRAN is written primarily in and contains over one million lines of code.
NASTRAN is compatible with a large variety of computers and ranging from small to the largest. NASTRAN was designed from the beginning to consist of several modules. A module is a collection of FORTRAN subroutines designed to perform a specific task—processing model geometry, assembling matrices, applying constraints, solving matrix problems, calculating output quantities, conversing with the database, printing the solution, and so on. The modules are controlled by an internal language called the Direct Matrix Abstraction Program (DMAP). Each type of analysis available is called a solution sequence. Example of MSC.Nastran analysis model Associated Software NASTRAN is primarily a solver for. It does not have functionality that allows for graphically building a model or meshing.
All input and output to the program is in the form of text files. However, multiple software vendors market pre- and post-processors designed to simplify building a finite element model and analyzing the results. These software tools include functionality to import and simplify geometry, mesh with, and apply loads and restraints.
The tools allow the user to submit an analysis to NASTRAN, and import the results and show them graphically. In addition to pre- and post-processing capabilities, several Nastran vendors have integrated more advanced nonlinear capabilities into their Nastran products. NASTRAN Options The following software options, based on NASTRAN original source code are available:. MSC Nastran. NASTRAN-xMG (acquired by ). (A PC/Linux-based version of the original NASTRAN source code). NX Nastran (acquired by re-branded to ).
Nastran distributed by the Open Channel Foundation MSC Nastran MSC Nastran is the original commercial Nastran product started by Dr. Richard MacNeal in 1963. MSC Nastran is commonly utilized for performing structural analysis. Although utilized in every industry, it maintains a strong following in aerospace and automotive industries for performing computational stress and strain analysis of component and system level models of structures. Since 1963, MSC Nastran has continued to evolve and extend capabilities to dynamics, rotordynamics, nonlinear, thermal, high impact, NVH, fluid structural interactive and fatigue analysis. Today it couples with and LS-Dyna to provide highly nonlinear coupled analysis solutions. NASTRAN-xMG Built from the same base code as the original NASTRAN software created by NASA that includes the original NASTRAN architecture and DMAP language, NASTRAN-xMG provides unlimited problem size, high-speed solver technology, and substructuring analysis options.
The principal founder of the company is Dr. NEi Nastran is a general purpose finite element analysis solver used to analyze linear and nonlinear stress, dynamics, and heat transfer characteristics of structures and mechanical components. It is available on a variety of platforms including 32/64-bit Windows and Linux. This software was acquired by in May 2014. NX Nastran NX Nastran resulted from an FTC action against MSC Corporation for alleged antitrust activity.
The antitrust settlement allowed the 2003 purchase of a royalty-free, perpetual license for the MSC.Nastran 2001 source code. UGS was previously the division of. Nastran's capabilities were added to and other components to form the EDS/UGS PLM Solutions suite. This product line was acquired by in 2007 and became. The purchase included a perpetual, worldwide, free of, nonexclusive license of the software program MSC.Nastran v2001, other assets related to the software, and all and rights acquired as a result of MSC's acquisitions of Universal Analytics Inc. And Computerized Structural Analysis & Research Corp. NX Nastran is now part of Siemens PLM Software's Simcenter 3D product portfolio.
OCF Nastran Both source and binary copies of Nastran are available from the for an annual license fee. This was part of the distribution from the. It was published in June 2015 on github, Off-shoots The success of NASTRAN led to development of many other finite element software. One such software is ASTROS that extended NASTRAN type capability to include structural optimization. Currently ASTROS is maintained by Zona Technology, Inc. Competition Currently there are numerous commercially available FEA products, some of them being able to read the NASTRAN input format although not bearing the name NASTRAN. Many of them are listed on the, and pages (see categories below).
