D3PLOT 22.1
Spring/Damper Geometric Data Components
Spring/Damper Geometric Data Components
D3PLOT cannot currently extract time-dependent data for these element types, (except normal force on stonewalls), so only geometric data components are available for them. These data are extracted from the . xtf file if present, or from the . ztf file if not. If neither file is present then these items will not be processed.
| LN_LIST_OF_NODES | TYPE_OF_SPRING |
In addition if the BEAM flag on the *DATABASE_BINARY_D3PLOT card may be used to write spring results into beam "slots" in the .ptf file as follows:
| BEAM = 0 (default) | Extra beam elements are added to the .ptf file using the spring/damper topology, and Global [Fx, Fy, Fz, Fr] forces are written in the Fx, Fy, Fz, Myy data "slots" for beams |
| BEAM = 1 | No extra beams are written |
| BEAM = 2 | Extra beam elements are written as for the "0" case above, but only the resultant force is written to the Fx "slot". |
If these extra beams are present in the database D3PLOT has no way of knowing whether they are genuine beams, or springs masquerading as beams. Therefore if you use this option treat your results with care.
