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 only have a microinjector available to me Femtojet eppendorf ( I am new this and have never used the instrument). I would like to create a negative pressure and aspirate spores. The idea is not...
