Hi there, I'm a beginner of Comsol.
Now I'm trying to calculate chemical reaction combined with normal chemical reaction module and the transport of duluted species module. My target is a reactants that maintains its position throughout the caluculation. I set properties all zero such as diffusivity, inflow and outflow, convection flow ...etc. However, it seems still have few diffusion of chemicals and it causes unexpected appearance.
I'm so glad if you can help me with an advice.
Best,
