MOOSE Newsletter (August 2025)

2025.08.05 Update

• Added support for vector-valued variables in MeshFunction, with regression testing for LAGRANGE_VEC, NEDELEC_ONE, and RAVIART_THOMAS cases.

• Added support for std::set values in Parameters

• Added generation of boundary condition ids in NetGenMeshInterface output

• Added support for sliding boundary nodes and higher-order elements to VariationalMeshSmoother

• Added SmoothnessEstimator, switched HPCoarsenTest to enable smoothness-aware hp adaptivity selection

• Fixed undefined behavior in ExodusII_IO input support for Bezier Extraction blocks

• Fixed support for configure --enable-glibcxx-debugging

• Added contains() and ends_with() utilities; used these to fix broken read support for files with base names of 4 characters or fewer.

• Changed GhostingFunctor containers to use vector rather than set, to avoid undefined behavior in functors that do parallel communication. Any application code that hard coded the previous container iterator return type may need to change to use auto or the new iterator typedef.

• Refactored add_periodic_boundary, added more error checking

• Optimizations in VariationalMeshSmoother

• Early-return optimization in RBEimConstruction

• Corrected link to DataTransferKit repository in DTKSolutionTransfer documentation

• Corrected configure --help output to reflect default-enabled status of Poly2Tri, Netgen, and Qhull

• Fix indentation in tests/Makefile.am

• Make sure dof index containers sized even when not active on block
