This option is used to specify a regularization scheme to mitigate potential mesh dependence of results in models that exhibit strain localization with increasing plastic deformation. It can be used only in conjunction with the *CLAY PLASTICITY option.

Set this parameter equal to the number of field variable dependencies, in addition to temperature, included in the definition of softening regularization. If this parameter is omitted, the softening regularization behavior may depend only on temperature.
Set TYPE=POWER LAW (default) to define the regularization behavior in terms of the crack band length, ; exponent, ; and bound on the magnitude of regularization, .
First line:
Crack band length, . This value must be greater than zero.
Exponent, . This value must be greater than zero.
Bound on the magnitude of regularization, . This value must be greater than zero.
Temperature.
First field variable.
Etc., up to four field variables.
Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than four):
Fifth field variable.
Etc., up to eight field variables per line.
Repeat this set of data lines as often as necessary to define the dependence of the softening regularization data on temperature and other predefined field variables.
