When you define field-dependent material properties (TBFIELD and related TB commands), the program uses linear interpolation between the data points you provide to determine specific material property values. To do so, the program:
Creates a grid using your defined field data values.
Assumes that you have defined curve-based data and automatically provides the missing grid data points.
Performs linear interpolation on this populated grid to find material property values.
Enables editing of the initialized field variables during solution, if necessary.
The following field-variable topics are available:
