The _ld.monitor file is an OptiStructASCII format results file.
File Creation
This file is created by default for any nonlinear run (similar to the
.monitor file).
File Contents
This file contains, for each nonlinear subcase, a table of the maximum translational
displacement for all grids (magnitude only) versus the load factor.
Formats
The following table format is used to print the monitoring information. The format is
a simple table with two columns: the displacement and the load factor. The values of
these two columns are basically the same as the .monitor file,
but the non-converged increments with cutbacks are not output. This file can be
opened directly in HyperGraph to plot the load factor
versus displacement curve.

Displacement
The maximum translational displacement of all grids (only
magnitude).
If an NLMON Bulk Data Entry is specified, with
GRID and corresponding DOF
parameters, then the displacement printed is at the specified component
at a particular grid. For more details, refer to
NLMON Bulk Data Entry.
Load Factor
This value is different from the Time Step or Time Increment. The load
factor is the subcase time normalized to the range of 0.0 to 1.0. The
Load Factor is also printed in the .monitor file.
The _ld.monitor file can be considered as a concise
version of the .monitor file.
