This MOOSE Newsletter edition is in progress. Please check back in April 2024 for a complete description of all MOOSE changes.

MOOSE Improvements

Added capability to read and write sparse matrices in the ASCII/Matlab format used by PETSc.
Added capability to read mesh constraint rows from an arbitrary sparse matrix. This will enable IGA solves on more flexible meshes without perfect body fit domains.
Added vector-valued parameter support in Reduced-Basis code.
Added normalization to Empirical Interpolation Method in Reduced-Basis code.
Removed redundant mapping code for FEXYZ. Instead use the common mapping code, which has additional optimizations, and which avoids a bug triggered by MOOSE use of those optimizations.
Fixed bugs in Tet14 element refinement with non-default diagonal selection.
Always number assembly element nodes contiguously when reading IsoGeometric Analysis meshes. This avoids a bug in transient IGA solves on distributed meshes with discontinuous assembly elements.
Minor bug fixes to example applications' common shell functions, test execution in configurations without numeric solver libraries, and an unused variable warning on newer compilers.
