DM.plotcprs
"Swiss Army knife" for manipulation or selection of d3plot file result data.
The tool enables the generation of new d3plot files from existing ones. For example the new database could be written without the stress tensors or velocities. It is also possible to remove parts from the data base. A common compression rate is 93%. The usage is recommended for: reduction of the database for faster transfer of the data, reduction of the database for final backup, facilitatation of data exchange with other parties by removing proprietary parts, creation of d3plot files in local coordinate systems, for example to fringe plot intrusion velocities.
plotcprs compresses LS-DYNA plotfiles by:
- optional eliminating result data on plot states
- optional selection of parts or part ranges
- optional coordinate box for elements to select
- optional transformation of nodal results onto a moving local system
- optional conversion of units for nodal results and any combination of these features
- result files may optionally be merged or splittet
