I am trying to create an OpenStudio measure the incorporates a solar hot water collector into a plant loop. I can create a new SolarCollectorFlatPlateWater object but cannot create a SolarCollectorPerformanceFlatPlate object.

Within measure.rb:

def run(model, runner, user_arguments)
  super(model, runner, user_arguments)  # Do **NOT** remove this line
  new_collector = OpenStudio::Model::SolarCollectorFlatPlateWater.new(model)
  new_collector_perf = OpenStudio::Model::SolarCollectorPerformanceFlatPlate.new(model)

This produces the following error in Ruby:

Error: allocator undefined for OpenStudio::Model::SolarCollectorPerformanceFlatPlate

Is there another way to create a SolarCollectorPerformanceFlatPlate object in an open studio measure?

I can't seem to get the code to look right. There are several lines that are all shown together but are separate lines.

OpenStudio automatically creates the performance object when you create the solar collector.

So:

new_collector = OpenStudio::Model::SolarCollectorFlatPlateWater.new(model)
new_collector_perf = new_collector.solarCollectorPerformance

You can find an example like this with more code here.

And of course the OpenStudio SDK documentation can be found here.

That fixed it. I also was able to use your code to do most of what I was planning to do. Thank you!
