Hello everyone,
I am trying to model the oxygen movement inside the blood stream. I am using Transport of Diluted Species with convection.
The equation I'm trying to model is
Where 
is the diffusion coefficient, 
is the solubility coefficient, 
is the velocity field of the blood, 
and 
are constants, and 
is a function with respect to pressure
My questions are 1. How do I get the partial pressure instead of the default concentration
2. In comsol, the term multiplied by the velocity field is the gradient of the concentration, how do I change it so that I have this whole term 
multiplied by the velocity field?
