thanks again for your answer

Js is a function of wall shear stress (known from solving Navier-Stokes)
D is the diffusivity (known)
u is the fluid velocity given by the Navier-Stokes (unknown but...

boundary condition at the wall

Hello,

I would like to model mass transport using convection-diffusion equation.
I want to apply a boundary condition of this type:
− D ∇c n + u c n = Js,
where c is the concentration, u the...
