NX Nastran (CAE/FEA)
NX Nastran is a Finite Element Analysis (FEA) and computer-aided engineering (CAE) tool provided by Siemens PLM Software.
Since the 1970s, the original version of NASTRAN has been one of many FEA solutions of choice in many major industries including aerospace, defense, automotive, shipbuilding, heavy machinery, medical and consumer products. It is currently one of many computer-aided software solutions (ALGOR, ANSYS, ABAQUS and MARC to name a few others) for the analysis of stress, vibration, structural failure, structural durability, heat transfer, noise, acoustics, flutter and aeroelasticity.
NX Nastran resulted from an FTC action against MSC Corporation for alleged antitrust activity which allowed the 2003 purchase of a royalty-free license for the software product MSC.Nastran by EDS, to the benefit of its UGS PLM Solutions division (subsequently spun-off from EDS and called UGS, and eventually Siemens PLM Software as of 2007). NX Nastran is based on the MSC.Nastran 2001 source code.
The purchase included a perpetual, worldwide, free of royalties, nonexclusive license of the software program MSC.Nastran, other assets related to the software, and all copyright and trademark rights acquired as a result of MSC's acquisitions of Universal Analytics Inc. and Computerized Structural Analysis & Research Corp. in 1999).
