hi friends

i want to define a mixture of gases (iodine,xe,radon) at inlet each with different concentration for diffusion in the air .
how can define mixture with different conc in comsol .

I think that you may define the composition of the gases as a function of the partial pressures.
I haven't done it yet, but if you have the concentration of each gas and the total pressure, you can calculate the partial pressures using Dalton's law.
So, once you have selected the materials, you can define in the physics part the pressure of each gas.
Greetings.
