Pull Request Overview

This PR updates boundary condition functions to support multi‐patch scenarios by modifying how temperature and Neumann functions are evaluated.

• In gsVisitorThermoBoundary.h, the conditional branch for evaluating temperature in the physical domain has been removed, and evaluation now always uses piece-based evaluation.
• In gsVisitorElasticityNeumann.h, a new variable (currentPatch) is introduced and assigned from patchIndex to allow multi‐patch evaluation of the Neumann function.

• [nitpick] Consider clarifying the inline comment for 'currentPatch' to explicitly explain its role in supporting multi-patch evaluation.

• The removal of the conditional branch may cause the evaluation in the physical domain to be skipped when paramTemp is false. Please verify that this change in temperature evaluation logic is intentional.
