I am modeling a rooftop package unit in Openstudio and noticed that when using a two speed DX cooling coil it causes the air loop details section of the Openstudio results to be skipped.

"Air Loops Detail section failed and was skipped because: undefined method `each' for nil:NilClass. Detail on error is in Measure Warnings section, if enabled at the bottom of this report."

"Air Loops Detail section failed and was skipped because: undefined method `each' for nil:NilClass."

Any Idea on how to prevent this?

Can you provide your OSM via e.g, Google Drive or Dropbox?

Has this issue been resolved? I'm having the same issue.

I (or rather AI) might have solved this by modifying the os_lib_reporting.rb in the resources folder. I've replaced the section below:

# Performance characteristics (specific to each component type)
