Before my modification, everything is normal, the simulation is smooth and the OpenStudio Results can be generated.
However, then I modified the setpoint schedules (cooling, heating, humidifying & dehumidifying). There were no complicate change, I just shortened the operation periods for the four schedules.
Then I ran the simulation and obtained the following figure.
Now even I change back the setpoint schedules, the simulation cannot go on.
Have anyone met this situation?
