Format of the Ansys LS-DYNA Databases Processed by D3PLOT
Format of the Ansys LS-DYNA databases processed by D3PLOT
D3PLOT processes four of the binary database file types from Ansys LS-DYNA:
| Complete state Dynamic relaxation Eigenvalue (ex Nike) |
.ptf
.rlf ---- |
Contains basic geometry and topology of, and transient results for, nodes, solids, shells, beams and thick shells. Eigenvalue files contain modeshape (not transient) results. |
| Contact force | .ctf | Contains geometry and topology of, and transient results for, contact surface segments. |
| Extra time history | .xtf | Contains geometry and topology of lumped-masses, springs, seat-belt types, stonewalls and joints. (But the results for these are not processed by D3PLOT.) Note that the .xtf file is not supported by MPP dyna, and that it is increasingly likely to be supplanted by the "binout" (or LSDA) database file. From V9.0 onwards the .ztf file contains all the plottable data previously extracted from the .xtf file, so there is no loss of functionality in D3PLOT. |
| CPG Airbag Data | d3dat | Contains information for CPG Airbag Particles including geometry and data components |
In addition D3PLOT also reads the following database file produced by PRIMER
| Pseudo time history | .ztf | Contains extra information culled from the input deck: nodal contacts, restraints and constrained, part and contact names. From V9.0 onwards also contains all static data previously saved in the .xtf file, making plotting of these extra items possible if an .xtf file is not present. The .ztf file is generated by PRIMER directly from the input deck, usually by running a batch translation phase immediately after the Ansys ls-dyna analysis. |
