Rationale

The gradient of the coupled variables should have a contribution to the Allen-Cahn system when the corresponding mobility or gradient energy coefficient is a function of the variable.

Description

A new kernel needs to be added to the Phase-field module that implements the following,
0.5 * (dLdu * kappa + L * dkappa_du) * |grad_v|^2

Impact

New capability.
