THE DATABASE

  FEMGV works with a structured database. For each model, the FEMGEN geometric data is stored in one database file and the FEMVIEW analysis results (including viewdata) are stored in a separate database file and a loadcase index file.

File names are installation dependent, generally the geometry data file will have a `.G61' extension and the results data files will have a `.V61' and a `.M61' extension. For example, a model with the name `FRED' will have a file for geometric data called `FRED.G61' and results files called `FRED.V61' and `FRED.M61'. For further information on file names, the user should consult his FEMGV distributor or refer to his FEMGV installation notes.

The viewdata in the results file consists of basic element and nodal point coordinate information and also special data sets constucted to support the interactive viewing facilities of FEMVIEW.. These special viewdata data sets may be created using element and coordinate data previously generated by FEMGEN or may be created from element and coordinate data obtained externally from an analysis program.
