Hi,

I am trying to co-simulate Dymola with energy plus where dymola is master and energyplus a slave. I have my HVAC system in Dymola and building model in energyplus and I want to input heating energy from HVAC to the building for which I am following simple case of "Configuring an EnergyPlus model which uses the Schedule object".I have made building model with ideal air loads as mentioned in the user guide. For some reasons the heat from dymola model is not getting in FMU model as I see there is no impact on temperature inside the building. The cosimulation is running but for some reasons the heating system is not responding as it should and I suspect there is something wrong in the energyplus file where heat in not getting inputed as schedule. I am attaching the idf file for the building model to get some feedback if I have not properly created the interface.

Please let me know if the energyplus file is correct. I would appreciate if i can also get some feedback on better way to co-simulate as with this one cannot divide heat input based upon convection and radiation (say for example in the case of radiator based heating).

Thanks,

Sanket

Hi Sanket,

you shouldn't have any HVAC system in your IDF file. Rather than that you should use the OtherEquipment object of EnergyPlus to input heat to your zone http://bigladdersoftware.com/epx/docs/8-0/input-output-reference/page-015.html#otherequipment. The OtherEquipment object should reference your schedule FMU_OthEqu_ZoneOne.

Best,

Thierry

Hi,

Do I need Zonecontrol" and "Thermostat setpoint" objects as well? the error I am getting now is attached in as image. Please check and suggest what could be wrong.

Thanks & regards,

Sanket
