NonconservedAction

Set up the variable and the kernels needed for a non-conserved phase field variable

This action simplifies the input file syntax for creating a nonconserved phase field variable in the phase field module. It creates the variable and all required kernels needed to solve for a nonconserved variable.

Variables

The name of the nonconserved variable is the block name.

Kernels

The kernels that are added are:
