Hi Francisco, You can represent any term explicitly in FiPy, including (f_y)^2. However, that sort of term might arise from a conservation law of the form (f f_y)_y. If that is the case, it is good to try and implement terms in their conservative form. In the case of (f f_y)_y, "f" will be a coefficient in a diffusion term.
