NX Nastran – Direct Matrix Abstraction Program (DMAP) is a unique Nastran programming capability available as an add-on to NX Nastran – Basic that allows customers to expand NX Nastran capabilities by writing their own applications and installing custom modules. DMAP can be used to compute additional measures of structural response; to transfer intermediate data to and from NX Nastran (for example, externally generated system matrices); to incorporate the latest software enhancements without waiting for a major software release; or to access more than just the standard results output sets.
