check-failed

Tabulated info about failed elements and NaN forces or NaN velocities.

This program checks the output files of the simulation (eg mes00xx) for all kind of failed elements. It gives a summarized information about failure reason (eg neg. volume, neg. jacobian) and properties of failed elements. Optional creation of session files for display and grouping of failed elements in Animator.


usage: check-failed [options] message-file[s]

options:

-xfail check for failed elements (default - turned off by "-xnan")
-list list with elements and times
-tstart <time> check only for failed elements after <time>
-tend <time> check only for failed elements before <time>
-pid give PID summary and PID for -list
-g <d3plot>
optional d3plot-file (needed for property info)
default: d3plot
-ide <opt>

create Animator3 session file for displaying elements that
failed during LS-DYNA run ("ide ele ###")
values for :
all - all failed elements
shell - failed shells
solid - failed solids
beam - failed beams
jacob - failed shells due to negative Jacobian
volume - failed solids due to negative volume
master - failed beams due to failed master segment (spotweld)

spotstp - failed welds due to unconstrained nodes   (spotweld)

-group create Animator3 session file for generating groups (Jacobian, negative volume, and other failed elements)
-xnan check for nodes with NAN values (="-xnanf -xnanv")
-xnanvelo check for nodes with NAN velocities
-version version info

Example:
% check_failed -l -pid mes*
