.monitor file

An OptiStruct ASCII format results file.

File Creation

This file is created by default for any nonlinear run.

File Contents

This file contains, for each nonlinear subcase, a table of the load increments, cutback information, number of iterations for each load increment, and the values of time increments and cutbacks and displacement results.

These displacement results pick the maximum value across all degrees of freedom, by default. Specific Grid and degree of freedom at which displacement results should be printed can be identified using the GRID and DOF parameters on the NLMON Bulk Data Entry.

File Format

The following table format is used to print the monitoring information.


Figure 1.
Name Content
SUBCASE SID Identification number of the Subcase for which the information is printed.
INCREMENT
NUMBER
Identifies the load increment number.
CUTBACK
Identifies if there was a cutback at a particular load increment.
"-"
Identifies that there is no cutback.
"C#"
Implies that a cutback occurred and “#” is a counter for the number of cutbacks.
CONVERGED
Identifies if a particular step is converged or not.
ITER
CONT
Number of contact iterations for each load increment.
EQUI
Number of equilibrium iterations for each load increment.
TOTL
Total number of iterations for each load increment.
TIME
INCR
Identifies the current time/load increment.
SUBCASE TIME
Identifies the current time/load inside a subcase (it is 0.0 at the beginning of a continued subcase).
CURRENT TIME
Identifies the current time/load for the entire model (continued subcases begin at the time at the end of the previous subcase).
LOAD FACTOR
This is the load factor. It can be considered as the subcase time normalized over the range 0.0 to 1.0.
MONITOR
DISP
Displacement output for each load increment. This value is output in the global coordinate system.
GRID
GRID identification number specified on the NLMON Bulk Data Entry.
DOF
Degree of freedom specified on the NLMON Bulk Data Entry.
