simulation in MoBi: concentrations and amounts do not match #686

Closed Mitmischer closed 3 years ago

Mitmischer commented 3 years ago

Hello,

in my particular simulation, I have the following values for my compound TCA and for the caecum (all in MoBi default units) Organism|Lumen|Caecum|TCA: 0.9027149 µmol Organism|Lumen|Caecum|TCA|Concentration in lumen: 12701.01 µmol/l. Organism|Lumen|Caecum|Volume: 0.000487745349439205 l.

If multiply the volume and the concentration, I get 6.1942777 µmol which differs a lot from Organism|Lumen|Caecum|TCA. What's wrong here?

I can provide the model if that helps.

The relevant Volume from which concentrations in Lumen are calculated is "Liquid Volume" (check the "Monitor" Info/Tab in the respective Observer):

That explains it, thank you :)
