Can I just implement what you've suggested? Would anyone require a discussion about this?
I don't know that it needs discussion; just a question of how to phrase it. Something like
the free energy of the system is based on a more general formulation (including concentration gradient energy) of that presented in Ref. ZHU...
I guess this would be the correct reference https://doi.org/10.1103/PhysRevE.47.1893
Agreed
...along with [ZHU] for the multi-phase
As reported by @daubners, the free energy in Benchmark 2 includes a term " $\frac{\kappa_{c}}{2}|\nabla c|^{2}$ " and says it is based on Ref. [ZHU] (and, indirectly, on Ref. [KKS]) and on Ref. [WBM]. None of these sources include a gradient energy term in concentration, although Ref. [WBM] does remark "a more general model might also include contributions due to the gradients of the other thermodynamic variables".
This term isn't "wrong", but it shouldn't be attributed to [ZHU] or [WBM].
Related: after Eq. (7), there is a typo in the coefficients: " $kc = k\phi = 3$ " should read " $\kappac = \kappa\phi = 3$. "
Note: these issues carry over from the original benchmark paper.
