Archive, ArchiveUnique, and ArchiveTime Commands

In MPM calculations, the calculation results are stored in a series of archive files. These files give periodic snapshots for the state of each material point. These files are required to post-analysis visualization. The Archive command determines where the archive files are saved and how often they are saved:

Archive (path)
ArchiveTime (time),<(first)>,<(props)>
<ArchiveTime (time2),<(first2)>,<(props2)>>
<ArchiveTime (time3),<(first3)>,<(props3)>>

or

ArchiveUnique (path)
ArchiveTime (time),<(first)>,<(props)>
<ArchiveTime (time2),<(first2)>,<(props2)>>
<ArchiveTime (time3),<(first3)>,<(props3)>>

where

A single ArchiveTime command is usually enough, but sometimes you want to archive infrequently at the beginning and then more frequently later or to archive by some other custom scheme. To create custom archiving schemes, you create archiving blocks with multiple ArchiveTime commands. Each subsequent command adds a new block that archives with new (time) and (props) settings in the first and optional third arguments. The new block starts at the time given in the second parameter, which is now a required parameter and it must be a later time than the start of the previous archiving block.

Notes

  1. (time) and (first) can alternatively be supplied as optional parameters in an Archive (path),<(time)>,<(first)> command or a ArchiveUnique (path),<(time)>,<(first)> command to define the root folder and archiving times in a single command.
  2. The Archive and ArchiveTime commands are only allowed for MPM analyses.
