KKS mass condition for multi phase

[LiuPengPeter]

Hello everyone,

I want to define the KKS mass condition for multi phase, like this:
c = h1x1 + h2x2 + ...
where c is the global concentration and x is the phase composition.

Is there kernel for this?

That's KKSMultiPhaseConcentration.
I forgot it!
