PDE as boundary condition

Hello,
I would like to solve a diffision / heat transfer problem where one of the boundary conditions is a PDE:
Boundary conditions:
at x=l
<-----
(this is the boudary condition for a well-stirred fluid or an ideal heat conductor)
Initial condition:
How do I implement this boundary condition in COMSOL (mathematics package)?
Best, Tobias
EDIT: Modified the equations such that they fit to the solution by Jeff.

Hello Tobias,
You can use a Flux boundary condition at x=l. See the attached file, where I non-dimensionalized everything (i.e. I took l=h=D=c0=1) and chose my own initial condition since you didn't say what it should be.
Best, Jeff

Hi Jeff,
Thank you so much, that's exactly the solution for my problem. I have edited the equations in my initial question such that they fit to your solution in case someone else has a similar problem.
Best, Tobias
