Hello everyone,

I am trying to solve a species diffusion problem for a focused stream. It seems that the diffusion of the species it is to slow compared to the analytical solution I have.
Do you have any suggestion for the source of error? the boundary condition are fine...I checked them many times.

Let me know if you need any other information about my problem set up

Thank for any help.
