Efficient implementation of the hybridized Raviart-Thomas mixed method by converting flux subspaces into stabilizations
Sreevatsa Anantharamu, Bernardo Cockburn
We show how to reduce the computational time of the practical implementation of the Raviart-Thomas mixed method for second-order elliptic problems. The implementation takes advanta…

Arnoldi-based orthonormal and hierarchical divergence-free polynomial basis and its applications
Sreevatsa Anantharamu, Krishnan Mahesh
This paper presents a methodology to construct a divergence-free polynomial basis of an arbitrary degree in a simplex (triangles in 2D and tetrahedra in 3D) of arbitrary dimension.…
