We are simulating a bio-barrier filtration system using this physics. The problem we are facing now is that we defined the equation of the growth rate of our bacteria in mathematics section, which has a "c" term in that, representing concentration of our contamination.
In the main equation of this physics, "Transport of dilute species in porous media", we have another equation already which has a "c" term.
We are wondering how we should define in COMSOL 5.0 that these two "c" variables are the same, showing the contamination concentration.
In better words, we want to globalize our variable "c' in order to be sure that in any place that COMSOL faces "c" considers it as the contamination concentration.
Thank you so much
