Hello, I want to solve a parabolic partial differential equation (i.e., mixed Richards' Eq): du/dt=d/dz(A(z)*du/dz+B(z)) I want to put a constraint so that all solution are greater than a constant value, c (u>c). I would be grateful if you help me.
Thanks, Abedeh

In R2016b one can use the Piecewise function. I hope that this helps you.
