Is it a bug of new version of Open Studio?

ScheduleConstant OutdoorAirCO2ConcentrationSchedule = new ScheduleConstant(model); OutdoorAirCO2ConcentrationSchedule.setValue(400); model.getZoneAirContaminantBalance().setOutdoorCarbonDioxideSchedule(OutdoorAirCO2ConcentrationSchedule);

Why it's failed and throw exception Description: C:\Git\OpenStudio_2\openstudiocore\src\model\ScheduleTypeRegistry.cpp@88 : No 'Outdoor Carbon Dioxide' Schedule is registered for class ZoneAirContaminantBalance.

Yes. With the shading surface group added the shading can be generated in IDF. Thanks.

It's the same with C#. Could you generate the shade in IDF using this code?

I use following code trying to generate the shade

Point3dVector points = new Point3dVector();

points.Add(new Point3d(0,1,0));
points.Add(new Point3d(1,1,0));
points.Add(new Point3d(1,0,0));
points.Add(new Point3d(0,0,0));

ShadingSurface shadingSurface = new ShadingSurface(points, model);

but no vertexes set from the generated idf

Shading:Building:Detailed,

  RightFin-{e996d645-5c20-47cf-8df8-faa8b9745cba}, !- Name

  ,                                       !- Transmittance Schedule Name
  ;

Anything else needs to be set to successfully generate the shade?

ThermlZone is translated. Ther ThermalZone has HVAC equipments.

Yes. Thanks very much. So it will call EPMacro.exe, ExpandObjects.exe energyplus.exe directly? What's the benefit compared with RunEp.bat?

And why Open Studio design a little bit complicated EP run framework like workflow, job? To be generic to support other engines in the future?

Yes. I create a OS:ThermostatSetpoint:DualSetpoint and I can see from the OSM file its been set to the thermozone.

Hi Macumber, is it possible that all the ScheduleYear/ScheduleWeek/ScheduleDay setting functions return true but the dualsetpoint and zonecontrol:thermostat not translated to IDF? It's difficult to debug what's the root cause? It's just not generated in IDF. I'm using the C# interface. Do you know how to debug it for these cases?

Actually I'd like to understand the way Open Studio dealing with the EnergyPlus results. 1. SqlFile to parse the SQL result and display in Runmanager. Is this the only way in Open Studio? 2. How OpenStudio triggers the EnergyPlus simulation? Is it also use the RunEP.bat in EnergyPlus or call the EnergyPlus.exe directly? Looks OpenStudio uses a lot of code like workflow, job in its RunManager.

Is SqlFile the only way used by Open Studio in RunManager to get the E+ result? And the only output used is the sql format?

Thanks. But the key issue is not resolved. Dualsetpoint and Zonecontrol:thermostat are not generated while the schedules are generated. At least all the set functions return true

I manually set the CalenderYear of YearDescription as 2009. All ScheduleYear setting return true. But there is still no ZoneControl:Thermostat in IDF

Is it because of "if (yd.assumedYear() != untilDate.assumedBaseYear()){ LOG(Error, "Assumed base year " << untilDate.assumedBaseYear() << " of untilDate does not match this model's assumed base year of " << yd.assumedYear()); return false; }"

But I can't get the assumedyear of YearDescription from C#. I know assumedyear of untilDate is 2009. How can I get the Open Studio log?

Add a scheduleweek to a scheduleyear sometimes success sometimes fail. I don't know why. Any restrictions for the scheduleday/scheduleweek?

Do I need to check the function return value each time? Will Open Studio throw any exceptions?No document or comment explain what exceptions will be thrown

I use the following code to add the schedules. "res1" and "res2" return false while "res3" and "res4" return true. I guess something wrong with the schedules. Open Studio doesn't tell users any message in this case which is not good. Date untilDate = new Date(new MonthOfYear(12), 31); bool res1 = coolScheduleYear.addScheduleWeek(untilDate, coolScheduleWeek); bool res2 = heatScheduleYear.addScheduleWeek(untilDate, heatScheduleWeek); bool res3 = dualSetpoint.setCoolingSetpointTemperatureSchedule(coolScheduleYear); bool res4 = dualSetpoint.setHeatingSetpointTemperatureSchedule(heatScheduleYear)

The OS:RunPeriodControl:SpecialDays is generated with Open Studio SDK, but in the translated IDF there is no this object? Does Open Studio support that?

I need to create a thermostat dualsetpoint But when I set ScheduleWeek for the ScheduleYear using C# code it's failed. After reading the source code, the problem is it will check the assumedYear. "if (yd.assumedYear() != untilDate.assumedBaseYear()){ LOG(Error, ..."

First question: Do I need to check the function return value each time? Open Studio does not throw exceptions? If throw where can I know what exceptions may be thrown for each function? How can I get the Open Studio log for debugging like the log in this example?

Second question: I know the assumedyear of the date is 2009. Then I set the yeardescription's assumedyear to 2009 too. The scheduleweek set successfully. Then two scheduleyears set for the OS:ThermostatSetpoint:DualSetpoint. But still no dualsetpoint and zonecontrol:thermostat in the IDF

Third question: What does assumedyear mean? Why do we check this?

Using the following C# code, there is always a System.AccessViolationException

Path path = new Path("D:\\IdealAirSystem.sql");

SqlFile sqlFile = new SqlFile(path);

Is this the correct way to use SqlFile? (The sql file exists at that path)

Do you mean the Open Studio version? It's updated.

Hi ,

I'm trying to register OpenStudio related dll as COM components so that I can call from other languages such as VB with RegAsm.exe provided by Microsoft. But there is an exception "Warning: No types were registered"

The ComVisible property in the AssembleInfo.cs should be set to true to resolve this issue. But I don't have this since the dlls are coming from the installation.

Anyone can help? thank

Can we specify the secondary air inlet not automatically set? No APIs open for this operation.

I know the node and also convert model objects like HeatExchangerAirToAirSensibleAndLatent.primaryAirInletModelObject to node

but I don't know what does HeatExchangerAirToAirSensibleAndLatent.primaryAirInletPort mean? Seems no port concept in Energy Plus.

In C++ the node can get from this airLoop.zoneSplitter().lastOutletModelObject()->cast<node>()

But in C# the related functions are not implemented as the compiler complains

public OptionalNode supplySplitterInletNode(); public OptionalNode zoneSplitterInletNode(int zoneSplitterIndex);

So I'm in trouble to find the following node and add AirTerminalSingleDuctParallelPIUReheat to it. Any one can help? Thanks

Thanks very much Macumber, due to the company policy I can't tell you the details at this stage.

I'm very sorry I have problems to use the C# API to call this function. Could you show me the code example to use this function?

With following code the function can't be recognized using OpenStudio; Model model = new Model(); getYearDescription(model);

Hi Macumber,

Thank you very much. For getYearDescription(model) do you mean it's a method of Model? There is no method named getYearDescription in the Model. Only one method public SWIGTYPEpboostoptionalTopenstudiomodelYearDescriptiont yearDescription();

I don't understand the type "SWIGTYPEpboostoptionalTopenstudiomodelYearDescriptiont".

I can set it using C++

openstudio::model::YearDescription yd1 = model.getUniqueModelObject<openstudio::model::YearDescription>(); yd1.setDayofWeekforStartDay("Sunday");

In C#, there is a class YearDescription But I don't know how to set it into the Model

Anyone can help? Thanks
