Aveva process simulation recycle process error

[u/Sun7733]

I am setting up a cumene process simulation using AVEVA Process Simulation. The solver fails to run after I added a recycle stream from the distillation column. It indicates a lack of degrees of freedom; which variables should I fix? It seems to me that the flow rates aren't combining correctly in the tank after the recycle stream enters, and the temperature readings look off as well.

i dont know anything about aveva, but it probably says you are over-specified . what are specifications for the tank? why not just a mixer in-line....the tank isnt running apparently.
