A multipoint stress-flux mixed finite element method for the Stokes-Biot model
Sergio Caucao, Tongtong Li, Ivan Yotov
In this paper we present and analyze a fully-mixed formulation for the coupled problem arising in the interaction between a free fluid and a flow in a poroelastic medium. The flows…

A Banach space mixed formulation for the unsteady Brinkman-Forchheimer equations
Sergio Caucao, Ivan Yotov
We propose and analyze a mixed formulation for the Brinkman-Forchheimer equations for unsteady flows. Our approach is based on the introduction of a pseudostress tensor related to…
