#run(scenario, force_clear = false) ⇒ Object

Create and run all SimulationFileOSW for Scenario. A staged runner is implented to run buildings, then transformers then district systems.

  • instantiate openstudio runner to run .osw files.

  • create simulation files for this scenario.

  • get feature_type value from in.osw files

  • cretae 3 groups to store .osw files (building_osws , transformer_osws , district_system_osws)

  • add each osw file to its corresponding group id simulation_dir is out_of_date

  • Run osw file groups in order and store simulation failure in a array.

parameters:

scenario - ScenarioBase - Scenario to create and run SimulationFiles for. force_clear - Bool - Clear Scenario before creating SimulationFiles.

return:

Array Returns array of all SimulationFiles, even those created previously, for Scenario.
