OpenStudio Analysis Gem
The OpenStudio Analysis Gem is used to communicate files to the OpenStudio Distributed Analysis.
The purpose of this gem is to generate the analysis.json file, analysis.zip, and communicate with the server to upload the simulations.
This gem does not create the cluster. Currently the only supported Cloud platform is Amazon AWS using either OpenStudio's PAT the openstudio-aws gem or using vagrant.
Instructions
There are two ways to create an OpenStudio Analysis description:
Use the Excel Translator
Programmatically
analysis = OpenStudio::Analysis.create
analysis.seed_model = "local/dir/seed.osm"
analysis.name = "Analysis Name"
# override existing workflow from a file by
analysis.workflow = OpenStudio::Analysis::Workflow.load_from_file(...)
# add measures to the workflow
wf = analysis.workflow
wf.add_measure_from_path("path_to_measure")
wf.add_measure_from_path("path_to_measure_2")
# or allow the system to search for the measure based on default_measure_paths
OpenStudio::Analysis.measure_paths = ['measures', '../project_specific_measures']
wf.add_measure_by_name('measure_name')
# make a measure's argument a variable
m = wf.add_measure("path_to_measure_3")
m.make_variable('variable_argument_name', 'discrete')
m = wf.add_measure('path_to_measure_4')
m.make_variable('variable_argument_name', 'pivot')
m.argument_static_value('variable_argument_name', value)
Testing
This gem used RSpec for testing. To test simply run rspec
at the command line.
Todos
In the programmatic interface there are still several items that need to be checked
- verify that the measure.xml file exists
- Check the type of measure being added and make sure that it is in the right workflow (e.g. no energyplus measures before rubymeasures)
- add reverse translator from existing analysis.jsons
- more explicit run workflows. For example, add workflow steps for running energyplus, openstudio translator, radiance, etc
- more explicit assignment of the analyses that can run. This would be nice:
a = OpenStudio::Analysis.create("new analysis") a.analysis_type('single_run')
