Controllable:No
Description:Chemical potential non-linear helper variable for the split solve
KKSSplitCHCRes
KKS model kernel for the split Bulk Cahn-Hilliard term. This kernel operates on the physical concentration 'c' as the non-linear variable
KKSSplitCHCRes is the split version. In this kernel, we calculate the chemical potential from . The non-linear variable for this Kernel is the concentration . To calculate and , we use the CoupledTimeDerivative and SplitCHWRes kernels, respectively, as described here.
Residual
In the residual routine we need to calculate the term . We exploit the KKS identity and arbitrarily use the a-phase instead.
Jacobian
On-Diagonal
Since there is no explicit dependence on the non-linear variable in the residual equation, the diagonal components are zero.
Off-diagonal
We are looking for the derivative of , where . We need to apply the chain rule and will again only keep terms with the derivative.
