Hello,
I am trying to apply a diffusive boundary layer as my upper bounary condition in my reaction transport model. My upper boundary should include an external concentration and a gradient.
The closest approach for my boundary condition is in this heat transfer model: https://www.comsol.com/blogs/modeling-natural-and-forced-convection-in-comsol-multiphysics/
However I don't see a simillar node when dealing with concentrations in a transort of diluted species physics.
Any suggestions?
Many thanks, Yaniv
