Defines values of field variables for material data tables.
Field variable type:
A frequency is to be specified in
A temperature is to be specified in
A time is to be specified in
A normal pressure is to be specified in
A total sliding distance (algebraic) is to be specified in
A total sliding distance (absolute) is to be specified in
A sliding velocity is to be specified in
A healing cycle number is to be specified in
User-defined field variable (UF01,UF02, ..., UF09)
XCOR / YCOR / ZCOR
X, Y and Z locations, respectively
Pressure degree of freedom
UX / UY / UZ
Displacements in the global/local X, Y, or Z coordinate system, respectively
The field value to be referenced (use this command multiple times to enter values of different field variables).
Define your data tables as field-variable-dependent (via the appropriate TB command), then issue the TBFIELD command to define the field values.
Define data values in ascending order for all field quantities. If a field value is to be held constant, define it only once; subsequent definitions are ignored.
No limit exists on the number of values that you can specify. The specified field value remains active until the next TBFIELD command is input.
After you have defined the field value(s), define your data for the data tables (TBDATA).

The TEMP (temperature) predefined field variable is available for all material models
defined via TB,
Lab. Several other field
variables are available for use with some material models (when used with specific element
types), such as TIME (time), PPRE (pore-pressure), XCOR / YCOR / ZCOR (location), UX / UY /
UZ (displacement), and UF01 - UF09 (user-defined). The field variables can be defined in the global coordinate system
or in any local or user-defined coordinate system.
