Possible bug in TimeStep in Openstudio 2.9.0

asked 2021-08-13 07:43:14 -0500

I have just notice that parameter Timestep in the OpenStudio settings is not being used in the simulation. For example, if I choose 6, this step is ok in the .osm file:

OS:Timestep,
  {210f49e8-ab04-4b81-b6fd-0fac6eeadcbc}, !- Handle
  6;                                      !- Number of Timesteps per Hour

But in the in.idf file it will always remain 4:

Timestep,
  4;                                      !- Number of Timesteps per Hour

Am I missing something?

I need to modify this value because I am using custom weather data with subhourly values. I guess the only workaround is to write a energyplus measure to modify this value.

Do you have other measures in your workflow? I know that the Timestep object is modified by things like tariff measures that need a specific timestep interval for demand widows.

I would check what @Eric Ringold suggests. There was an old issue where GUI showed different default value than was used if not specifically entered, but that was fixed in 2016. https://github.com/NREL/OpenStudio/is...

Thank you very much for your comments. You were right. I was also using a tariff measure that was changing the timestep.
