EnergyPlus™ is a whole building energy simulation program that engineers, architects, and researchers use to model both energy consumption and water use in buildings.
The EnergyPlus program may crash when the stratified water heat tank inputs are set to autosizing some input parameters such as tank size and height. The issue can be demonstrated by the attached .idf file which is slightly modified from the example file 5ZoneWaterSystems.idf: in the file a stratified water heater replaces the original mixed water heat in the example 5ZoneWaterSystems.idf file.
The temporary workaround is either switching to a mixed water heater (WaterHeater:Mixed), or setting the stratified tank size and height values manually.
