How to insert a first order concentration derivation to an equation in COMSOL?

Hi

I asked a question in this forum before, but unfortunately I didn't receive any response, maybe it was not a clear question. So I will change my question and asked something more general. I want to add a first order concentration derivation to an built in equation in COMSOL. How can I add this component?

Thanks,

Negin

Hi

there are I asume two ways, one is to turn ON the Preferences Equation View and ten edit the undedrlyi ng COMSOL equations

the other (TBC) would be to find a contributive BC where you add the concentration derivative, but I'm not sre this will work, certainly model dependent

Good luck
