I am using Comsol Multiphysics 3.5a to model a physical absorption. I chose the che chemical engineering module/ mass transport/ convection and diffusion. I want to know how to set the reaction rate in Sumdomian settings for physical absorption? Hope any professional friends can give me some help. Thans a lot!

Hi Yunshan,

I'm using comsol for modeling Dielectric barrier discharge.I have a problem in inputting reaction too.May be you can help me.
For plasma the initial condition is that it be neutral but when i have some ions and i want to set this condition , i set initial value all ions equal electron but comsol cant not be run and i don't know how do must i.
please if you can reply me.
Best regard,
Azadeh
