Hello,
I am modeling microorganiamo growth in a bioreactor, using the Chemical Engineering Module.
The question is, as time passes, the organism grows and feeds on a substrate, the substrate concentration goes down to 0. The thing is, if the simulation continues, the concentration is negative and I do not want that to happen.
In short, how do you do for the variable does not acquire negative values?
Sorry for my bad English. Thanks.
