Hi, I am following video tutorial https://www.youtube.com/watch?v=BG-dkp7z1fI

pitzdaily case.

See 6:24

Error:
Unable to set reference cell for field p
Please supply either pRefCell or pRefPoint

Why is this needed? It is not in the tutorial.

I have noticed there exists a topic about similar problem, but not with pitzdaily and they did not mention what exactly they changed in the fvSolution.

Just a moment, I will send the code.
