## Classes

class  CoupledSwitchingTimeDerivative
This kernel adds a contribution $$\left( \frac{\partial F_a}{\partial \eta_{ai}} f_a + \frac{\partial F_b}{\partial \eta_{ai}} f_b + ... \right) \frac{\partial \eta_{ai}}{\partial t}$$ where $$a,b,..$$ are the phases, $$h_a, h_b,..$$ are the switching functions, $$\eta_{ai}$$ is the order parameter that is the nonlinear variable, $$t$$ is time, and $$F_a, F_b,..$$ are functions for each phase.
