ToArchive Command

In MPM calculations, the solution is stored in a series of archive files. These files give all the current calculation results for each material point. These files are read latter to plot the results. The Archive Command selects where and how often the files are saved. The ToArchive command described here selects which analysis results are saved in those archived files:

ToArchive (data1),(data2),...

where any number of parameters specify which data to archive by name. You can put all options in a single ToArchive command or put them in multiple ToArchive commands. The archiving options, which are case insensitive, are:

The follow options are for crack particles:

Certain material point results are always archived and thus there is no need to specify them in a ToArchive command. The standard archived data are:

Notes

  1. If a commands file has no ToArchive command, it will archive default properties, stress, strain, and velocity. If ToArchive commands are used, the default stress, strain, and velocity will be replaced by all options in those commands.
  2. The visualization tools handle conversion of any archived files to a good set of units. You can also change length and time units for visualization if desired.
  3. There are no options for archiving kinetic energy because it is easily calculated in visualization software from mass and velocity. Thus, to do kinetic energy plots and calculations, you must archive particle velocity.
  4. Plots of total energy require archiving strain energy and velocity (the latter to get kinetic energy).
  5. The ToArchive command is only allowed for MPM analyses.
