V26.2.0-IOFreeze: new Absorptance Inside Face fields

[joseph-robertson]

Pull request overview

• Fixes #ISSUENUMBERHERE (IF THIS IS A DEFECT)

Pull Request Author

• Model API Changes / Additions
• Any new or modified fields have been implemented in the EnergyPlus ForwardTranslator (and ReverseTranslator as appropriate)
• Model API methods are tested (in src/model/test)
• EnergyPlus ForwardTranslator Tests (in src/energyplus/Test)
• If a new object or method, added a test in NREL/OpenStudio-resources: Add Link
• If needed, added VersionTranslation rules for the objects (src/osversion/VersionTranslator.cpp)
• Verified that C# bindings built fine on Windows, partial classes used as needed, etc.
• All new and existing tests passes
• If methods have been deprecated, update rest of code to use the new methods

Labels:

• If change to an IDD file, add the label IDDChange
• If breaking existing API, add the label APIChange
• If deemed ready, add label Pull Request - Ready for CI so that CI builds your PR

Review Checklist

This will not be exhaustively relevant to every PR.

• Perform a Code Review on GitHub
• Code Style, strip trailing whitespace, etc.
• All related changes have been implemented: model changes, model tests, FT changes, FT tests, VersionTranslation, OS App
• Labeling is ok
• If defect, verify by running develop branch and reproducing defect, then running PR and reproducing fix
• If feature, test running new feature, try creative ways to break it
• CI status: all green or justified

[Copilot]

🟡 Changes recommended

The blank Material:NoMass reverse-translation test uses incorrect field indices, invalidating its fallback assertions.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

Adds inside-face absorptance support for standard and massless opaque materials, including blank-value inheritance and EnergyPlus translation.

Changes:

• Extends the model schema and APIs with three inside-face absorptance fields.
• Adds forward and reverse translation support.
• Adds model and translator tests.
