GlobalArchive and GlobalArchiveTime Command

In MPM calculations, the solution is stored in a series of archive files (see Archive Command). You can optionally create a global results file which will store a collection of calculated results such as average stress, total energy, etc., in a single file. The file is tab delimited with the time (in alt time units) in the first column and all requested results in subsequent columns. This file can be opened later and plotted by this software or by any spread-sheet software. The GlobalArchive and GlobalArchiveTime commands selects which analysis results are saved in the global results file and how often they are saved:

GlobalArchive (quantity),<(mat)>
GlobalArchive (quantity),(x),(y),<(z)>
GlobalArchiveTime <(time)>

where

The global archiving quantities, listed by category are:

Note: when global archiving of strains, they are calculated as a Biot strain in the current configuration. The Biot strain is defined is V-I where V is the left-stretch tensor. This strain is also the Seth-Hill strain with m=1/2 in current configuration. For small strain problems it is equivalent to the small strain tensor.

Notes

  1. You can store as many quantities as you want in the global results file by having any number of GlobalArchive commands, but only one option can be in each command.
  2. All all terms involving heat ("Heat Energy", "Entropy", "Internal Energy", and "Helmholz Energy") will only the physically correct if all materials have specified their heat capacity.
  3. The GlobalArchive and GlobalArchiveTime commands are only allowed for MPM analyses.
