I have modeled a standard residential building (a single-family home) with PCM inclusions ( the old PCM model) and exported the idf from BEopt. After exporting I have reduced the model to focus on the west facing wall of the living zone. This wall only would include PCMs. The model ran normally and gives desired results.

As the next step I wanted to run this model implementing the new PCM model with hysteresis. Hence, I have made a new object in MaterialPropertyPhaseChangeHysteresis for ExtWallMass and filled in the necessary information. Then when I ran the program It crashed.

Afterwards I removed the ExtWallMass objects from MaterialPropertyPhaseChange and MaterialPropertyVariableThermalConductivity just in case and still it crashed. I have attached the construction object I run for the west facing external wall which now includes the only PCM inclusion. I have also attached the idfs I am working on E+ 8.8 with the old PCM model which runs well and the hysteresis PCM model which crashes.

Are there other changes in the IDF required to replace the old PCM properties with Hysteresis model object?
