I have my simulation model for a simple building room using PCM on the floor surface. I used the MaterialProperty:PhaseChange which requires the Field Set: Temperature-Enthalpy as an input. This setting is different from the MaterialProperty:PhaseChangeHysteresis where I can check the PCM states in the output of CondFD Phase Change States image description

So, is there any way to check the changing states between liquid and solid of a PCM when I use the MaterialProperty:PhaseChange as an input?

@fransmich have you tested if this CondFD Phase Change State output variable can be generated from your EnergyPlus model with PCM? It might be something generated when you use the CondFD (Conduction Finite Difference) heat balance algorithm in general, regardless of other model details.
