Jul 1, 2025July 2025 monthly summary for idaholab/moose: Implemented robust error handling for out-of-bounds conditions in temperature and specific volume by replacing mooseError with MooseException when _OOBBehavior is Throw. This bug fix improves error reporting, debuggability, and user feedback for boundary conditions. Commit ce974885d207c4f382416e701dc2c59ebe9cbbde (turn error to exception for out-of-bounds behavior on temperature; closes #31070). This aligns with the project’s exception-based error handling strategy and reduces risk of silent failures in critical simulations. Business value: more reliable simulations, faster debugging, and clearer failure signals in boundary scenarios.

May 1, 2025Deliverables for 2025-05 include a unified AD/non-AD NodeElemConstraint framework with base classes and Jacobian support, enabling consistent constraint handling across contexts and improving maintainability. Enhancements to NodeElemConstraint added writable variables, variable scaling in Jacobians, and multi-variable coupling tests, with tests validating AD vs non-AD behavior and cross-domain scenarios. A safety guard prevents using Automatic Differentiation with kinematic constraints, with explicit error handling. Documentation updates and code refactoring consolidated common functionality into base classes, reduced unused code, and expanded test coverage. These changes provide stronger solver reliability, enabling more complex simulations with multi-variable constraints while maintaining performance and correctness.
