Source Term

Hi,
How do I add a time and space-dependent source term?

What equation do you want to solve and what have you tried so far?

I want to solve a diffusion-reaction equation with a source of form d_t u(x, t) = d_x^2 u(x, t) + u(x, t) + f(x, t); here, d_t and d_x are the partial derivatives w.r.t x and t. I did not find any option to include f(x,t).

You can simply use the PDE class to define your PDE with a right hand side that depends on time and space.
