Jul 1, 2025July 2025 performance snapshot: Completed a major refactor of the Raviart-Thomas bubble space to support anisotropic polynomial representations (PolynomialsVectorAnisotropic) and harmonized with FE_RaviartThomas lexicographic numbering. Updated PolynomialsRT_Bubbles to adopt the new representation and simplified the API by removing explicit polynomial ordering vectors, plus eliminated unused code to improve maintainability. The changes lay groundwork for future anisotropic polynomial support and potential performance improvements across RT bubble representations.
