How can I express free outflow boundary in Classical PDEs module?

Hi

I'm trying to couple new physics to Darcy's law by using Convection-Diffusion Equation in Classical PDEs.

Since there is no predefined outflow boundary condition in this physics, I have to define the free outlet boundary which satisfy 'normal flux equals zero'.

I've tried to define this by using Constraint node, but I was not able to find out how to define it. I'll be appreciated for any information about solving this problem.

I attached some pictures about my situation.

Thanks.
