restrict codomain of dependent variables, i,e. make them positive always?

I have a model with ion concentrations as dependent variables amongst others. When solving my problem, COMSOL makes one of the concentrations negative! But it can only be posititve of course. So, how can I restrict the codomain of my dependent variable, i.e. tell COMSL that making the it negative is not allowed?
All best and thank you very much for your answers,
