Hello all.
I want to simulate arterial wall (free wall model) and so I should to define mass transfer condition in wall .( I need to have suction velocity=4e-8 m/s and diffusion coefficient= 5e-8 m^2/s)
my geometry is a cylinder.
my boundary condition:

At inlet I have specific concentration.
at outlet I have no change in concentration.
at wall my concentration comes from mass transfer equation.
How I can simulate this problem in CFX ?????????????
Pleas answer to me.
I really need to know
