Why Dynamic Simulation doesn't Initialize?

Hi Guys

I find a funny thing:

I do the dynamic simulation, apply bus disturbance. The result show me, bus 2 voltage is 0.719 pu.
After first simulation, I do another simulation, with same dyr & sav file, I choose a different Channel output file and Initialize it. Without apply any bus distrubance, the bus 2 voltage is still 0.719pu...?

It is normal for PSSE? How to avoid this issue? Thank you very much.

Have you opened the orignal saved case again after the first simulation?

The problem is that the fault is still applied at the bus 2. Check network data and you will find a fault shunt at the bus, inserted during the first simulation.
