📌 .NAS format standard corresponds to the input file utilized and opened up by MSC Nastran, a comprehensive, complex program suite for structural analysis. In practice, the .NAS items include input bulk content definitions associated with MSC Nastran to properly analyze the strain and stress of components and models of structures that correlate with the system level of research. Within .NAS extension mechanics the data is visually represented and opened up in the FORTRAN programming language, which was initially designed by IBM, and is abbreviated from the Formula Translating System term. Besides, the .NAS file samples also consist of plenty of miscellaneous forms of information, such as the node locations of the .NAS elements that make up the models, the quantity of grids, the name identifier of the bulk data, and so forth. On the constitution and layout, the .NAS file structure is quite close to .DAT and .BDF records, which are applied to input data with the interaction of MSC Nastran models.
📌 The .NAS data elements can be accurately reviewed, opened up and revealed by MSC Nastran program bundle which serves as a top-level software toolset for finite element analysis (FEA) purposes applied to analyze the custom data structures and models. Initially, the .NAS compatible MSC Nastran distributive was intended to be employed by NASA in the 1960s but since that period of time the project has significantly advanced and begun spread across MSC Software corporate group. The .NAS file specification is compatible with Windows and Linux operating systems. Nastran utility offers plenty of unique tools to optimize, fix, test, and design various structural designs and entities. You can construct and implement virtual .NAS prototypes to resolve structural problems and misfits during a product’s service period to reduce downtime, optimize the actual performance of existing designs, and save money instead of building the real physical prototypes. The .NAS tech principle also magnificently fits for fatigue analysis.
