Reactor duty for sub class modelling of CSTR

[Omotola94]

Describe the bug
It keeps on bringing this error 'divide by zero encountered in scalar divide'

To Reproduce
Reactor model.txt

Expected behavior
I want it to simulate with an expected increase in temperature and constant pressure and produce auxiliary units just like the continuous fermentation example on BioSteam

Actual behavior

Version
Using google colab biosteam==2.43.1

Additional context
Please I will appreciate if the code or script can be modified to having auxiliary units and runs well, i have tried following the the example on continuous fermentation but i seem to be missing out something
