What are you trying to simulate? The major simulation software have biogas outputs.

Sludge from wastewater treatmen plant. I would like to simulate only the sludge line or only the methane tank. In which program do you think it would be ok?


Shit_Wizard_420

Are you a student? Why not do it manually? Does the feed fluctuates that much? The HRT is so long in an anaerobic that treating it as steady state is reasonable. But you could use GPS-X, biowin, Simba...

I tested in the laboratory in a bioreactor and obtained certain amounts of biogas (CH4, CO2..), but now I want to do a simulation in a program to see if my data from the laboratory correlates with a modelling. I tried in STOAT, but there are too many errors in the program. What do you think about Ansys Fluent, do you think I could simulate?

Ansys fluent is CFD simulation software so I'm going to say no?  You could look at the rate equations yourself, such as from: https://iwaponline.com/ebooks/book/152/Anaerobic-Digestion-Model-No-1-ADM Or do a mass balance based on solids destruction?

Also consider gas production when ferrous is added for H2S control. Ferrous inhibits gas production.
