I tested example file HybridZoneModel.idf and see that there is not available output for Calculate Zone Internal Thermal Mass. Checking source code ZoneTempPredictorCorrector.cc#L5900 - I found time step output ZoneVolCapMultpSensHM ZoneTempPredictorCorrector.cc#L5946 inside InverseModelTemperature function for Internal Thermal Mass option while HybridModel.unit.cc also this properties for Hybrid model internal thermal mass (free-floating) testcase HybridModel.unit.cc#L287. I wonder if there is any way to get such output in output of EP run or I should build EP source code to get it for such case?
