A mixed finite-element discretisation of the shallow-water equations [PDF]
Geoscientific Model Development, 2023 This paper introduces a mixed finite-element shallow-water model on the sphere. The mixed finite-element approach is used as it has been shown to be both accurate and highly scalable for parallel architecture.

A family of H-div-div mixed triangular finite elements for the biharmonic equation
Results in Applied Mathematics, 2022 A family of Pk+22×2-PkH(divdiv)mixed finite elements on triangular grids is constructed for the biharmonic equation. For the H(divdiv)mixed finite element functions, both the stress tensor and its divergence have continuous normal components, σh⋅nand ...

RECTANGULAR MIXED FINITE ELEMENTS FOR ELASTICITY [PDF]
Mathematical Models and Methods in Applied Sciences, 2005 We present a family of stable rectangular mixed finite elements for plane elasticity. Each member of the family consists of a space of piecewise polynomials discretizing the space of symmetric tensor fields in which the stress field is sought, and another to discretize the space of vector fields in which the displacement is sought.
