Hi,I have a simulation of a one stage hydrocracker on hysys and i want to take it to dynamics from steady state so as to control the temperature but the dynamic assistant is saying the unit peration cant be taken to dynamics,..please what can i do?

I think the dynamics assistant also includes a summary of what items are causing the conflict. Usually it because you have specified as static certain items that need to be dynamic. For example, pressures. If all the pressures are fixed, there is nothing "dynamic" that the simulation can do. You can start off by adding valves at inlet and outlet of the equipments. You can also watch youtube videos on how to create dynamic simulations.
