I am trying to simulate a patient with COPD and notice that when I run the simulation for more than 1200 seconds I get a message saying that the patient’s stomach is out of sodium. Is there a way to make sure that this doesn’t happen?

You don’t really need to worry about this, its just an informative message from our digestive system.
