MSC Nastran is a multidisciplinary structural analysis application used by engineers to perform static, dynamic, and thermal analysis across the linear and nonlinear domains, complemented with automated structural optimization and award winning embedded fatigue analysis technologies, all enabled by high performance computing.
Engineers use MSC Nastran to ensure structural systems have the necessary strength, stiffness, and life to preclude failure (excess stresses, resonance, buckling, or detrimental deformations) that may compromise structural function and safety. MSC Nastran is also used to improve the economy and passenger comfort of structural designs
A file with extension X_T (Parasolid text files) is used by the Parasolid core created by Siemens PLM Software. It is being developed as a standard export format for distributing Parasolid CAD models.
The X_T file is a set of structured data containing information about the features of the model construction, the topology of its structural elements, color scheme, coordinates of drawing primitives, etc.
The X_T extension is unpretentious to adapt and can be exported / imported for use in a wide variety of CAD systems. It is stored in text format and can be exported and imported using a variety of other computer-aided design programs.
X_T files are used instead of the old version of the XMT_TXT and XMP_TXT files, which are less used than X_B (Parasolid binary files), and store the same data, but in binary format.
A CAD file is an output of a CAD software, containing key information about the designed object: its geometry and topology representation, 3D model hierarchy, metadata, and visual attributes depending on the format of the file.Read more
