Unconditionally Stable Mixed Finite Element Methods for Darcy Flow
Maicon R. Correa, Abimael F. D. Loula
Unconditionally stable finite element methods for Darcy flow are derived by adding least-squares residual forms of the governing equations to the classical mixed formulations. The…

Stabilized velocity post-processings for Darcy flow in heterogeneous porous media
Maicon R. Correa, Abimael F. D. Loula
Stable and accurate finite element methods are presented for Darcy flow in heterogeneous porous media with an interface of discontinuity of the hydraulic conductivity tensor. Accur…
