Unable to use .solve method for Coupling Boundary Condition of one PDE with source term of another PDE

Hi all, We have been working on modifying Jonathan's gist* code (crazycoupling2.ipynb) of how to couple the PDEs along the upper boundary of a 2D mesh, i.e. wherein one PDE is along the x-axis and the oth

RE: Model convection with non-linear adsorption

Dear Daniel, Thanks for looking into this. I sent you an MWE of my actual code to keep things as simple as possible, apparently too simple. Indeed in my actual code the variables are updated. Furthermore, I also implemented some adaptive timestep. But that did not help much. Timesteps can only
