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 by UGS. UGS was previously 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 life-cycle management suite. This product line was acquired by SIEMENS in 2007 and became SIEMENS PLM Software.
