Hello

I'm trying to simulate lng heat exchanger in UniSim design. I have not enough data for dynamic simulation so I tried to calculate it in steady state. I have temperatures for all streams (there are one hot stream and two cold ones). But I don't know UA. Is it possible to take data from steady state to dynamic mode using only geometric sizes and stream temperatures?

Thank you

UniSim will calculate UA values from your steady state simulation. You can use the values in dynamic mode.
