Hello,

I am solving a 1D convection-diffusion equation using the Classical PDE set up. My equation has a source term. The left BC has a zero flux, while the right BC has a dirichlet condition of u = 0. Since the left BC has zero flux, the concentration u will increase with time due to the source term. How can I limit the concentration on the left boundary to a specified value so that as time increases, the concentration there is capped at the threshold?

Thanks.


Best wishes,

EH
