I am currently working on optimising my FCC unit in Hysys. However, after inputting all my variables in the 'Original Optimizer configuration', my system takes my upper bound as my optimum value or does not converge at all.
I would like to know how one can mathematical prove that chimney effect does take place when having a ventilated foundation with high pipes on the warmer side of the building and low pipe on the...
