The following keywords specify time-history output (ASCII format) for an explicit dynamics analysis. The time history files output are requested through Time History Output Controls section of the Analysis Settings . Up to 10 ASCII files can be requested in the GUI. The sampling time is calculated from the number of values requested and from the end time of the simulation.
The results files ( GLSTAT , BNDOUT , RCFORC , SPCFORC , MATSUM ) are always output by LS-DYNA. The sampling frequency can, however, be modified.
*DATABASE_HISTORY_NODE_SET
Controls which nodes or elements are output into the binary history file and the ASCII file NODOUT for a particular result tracker.
Card
ID1 = the ID of the component defined by the result tracker object.
*DATABASE_BNDOUT
Specifies the sampling parameters for the BNDOUT results file (stores Boundary condition forces and energy).
Card
DT = End Time divided by Value from the Time History Output Controls section of the Analysis Settings.
*DATABASE_DEFGEO
Specifies the sampling parameters for the DEFGEO results file (stores Deformed Geometry Data).
Card
DT = End Time divided by Value from the Time History Output Controls section of the Analysis Settings.
*DATABASE_DEFORC
Specifies the sampling parameters for the DEFORC results file (Discrete Elements Data).
