ACInterface2DMultiPhase1

Gradient energy Allen-Cahn Kernel where the derivative of interface parameter kappa wrt the gradient of order parameter is considered.

Implements the Allen-Cahn term for the gradient energy contribution for the anisotropic interface energy case. Its weak form is where (kappa_name) is the gradient energy coefficent, the non-conserved non-linear order parameter variable the kernel is acting on, (mob_name) is the scalar (isotropic) mobility associated with the order parameter, and is the test function.
