Walkthrough

This PR introduces Heat Transfer Coefficient (HTC) as a new interpolated load type. The implementation adds HTC to the configuration enum, extends template selection to return CONV and TEMP modes for HTC, and provides comprehensive test coverage with sample destination mesh and HTC source data files.

Changes

HTC Interpolation Feature

Layer / File(s)	Summary
HTC Load Type Definition src/interpcore/config.py	Adds INTERPOLATED_LOAD_TYPE.HTC enum member and extends __post_init__ to set num_components = 2 for HTC configurations.
Template Selection for HTC src/interpcore/interpolator.py	Extends _select_template() to return two ANSYS templates (CONV and TEMP modes) when HTC load type is selected.
HTC Test Coverage and Sample Data doc/htc/destination_mesh.txt, doc/htc/source_data/htc_data.txt, tests/test_interpolator.py	Provides sample node mesh coordinates and HTC/Tref source data, plus test fixtures and three new test methods validating HTC interpolation, ANSYS export output, and template selection.

Poem

🐰 A heat coefficient hops into place,
With templates and configs in perfect grace,
Two components dancing, CONV and TEMP align,
Tests validate each node coordinate line,
Another load type conquered—the interpolator's divine! 🌡️

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title 'add interpolation of HTC and T bulk' clearly summarizes the main change: adding HTC interpolation support. While 'T bulk' is mentioned in the title but 'Tref' (reference temperature) appears in the data files, this is a minor discrepancy. The title accurately captures the primary objective of the PR.
Docstring Coverage	✅ Passed	Docstring coverage is 87.50% which is sufficient. The required threshold is 80.00%.
