*EXTREME NODE VALUE
Define nodal variables to be monitored.

This option is used to define nodal variables that are to be monitored and compared with user-specified values. It must be used in conjunction with the *EXTREME VALUE option.

Product: Abaqus/Explicit  

Type: History data

Level: Step

References:

Required parameter:

NSET

Set this parameter equal to the name of the node set in which the variables are to be monitored.

Required, mutually exclusive parameters: 

ABS

Include this parameter if the user-specified value is to be the upper bound for the absolute value of the variable. At every increment Abaqus/Explicit will check whether the absolute value of the variable has exceeded the specified value.

MAX

Include this parameter if the user-specified value is to be the upper bound for the variable. At every increment Abaqus/Explicit will check whether the variable has exceeded the specified value.

MIN

Include this parameter if the user-specified value is to be the lower bound for the variable. At every increment Abaqus/Explicit will check whether the variable has fallen below the specified value.

Optional parameter:

OUTPUT

Set OUTPUT=YES (default) if the requested field-type output to the output database and an additional restart state are to be written when any variable value exceeds the user-specified bounds for the first time. The output will be written in the increment following the one in which such an occurrence took place.

Set OUTPUT=NO to prevent any output from being written.

Data lines to define nodal variables and the maxima or minima: 

First line:

  1. Give the identifying keys for the nodal variables to be monitored. Any variable available for history-type output to the output database can be specified. The keys are defined in “Abaqus/Explicit output variable identifiers,” Section 4.2.2 of the Abaqus Analysis User's Guide.

  2. Enter the extreme value.

Repeat the data line as often as necessary to define additional variables to be monitored and their maxima or minima.
