I am simulating a porous cylindrical material which is filled with oxygen and has two outlets at atmospheric pressure.
I want to add the concentration/pressure of oxygen in the body.
Can anyone tell me, how can I achieve this?

If the fluid is just oxygen then use boundary conditions or initial conditions to specify the pressure state for the simulation to use.

If the fluid is a mixture of oxygen and other gasses (air, for instance) and the concentration of gasses varies around the simulation then consider using a multicomponent mixture for the fluid as that can handle variable composition gasses.
