HYSYS Dynamic Initialization

I have a model that drifts a bit from my initial settings. Instead of going back to steady state to reinitialize I would just like to set the values.

I put a stream off by itself and specified the composition, temp, and pressure. I used this stream to initialize other streams. I had to do it this way because I didn’t have a suitable stream that was 100% vapor after running the dynamic model.

This isn’t working for me. 2 questions:
1. When is dynamic initialization done? Is this after cycling from stopped to start? Does it have to be “reset” to time zero?
2. Mine is failing but with no error, it just doesn’t reset to my values no matter what I do. Any suggestions?

Greatly appreciated !
