Assuming I have a model with initial concentration of $c_0(x)$, I would like to model a point sink for this case (considering the velocity is neglected :D) $$\frac{\partial c}{\partial t}=D\frac{\partial^2 c }{\partial x^2}-\delta(x)c$$ I am wondering if the last term can represent a correct sink term for this problem considering we have a well where we are producing from $x=0$ point. Second, I am not sure how to take care of sink term with Green function.
