A posteriori error estimates for the Brinkman-Darcy-Forchheimer problem

04/28/2021 ∙ by Toni Sayah, et al. ∙ 0

In this paper, we study the "a posteriori" error estimate corresponding to the Brinkman-Darcy-Forchheimer problem. We introduce the variational formulation discretised by using the finite element method. Then, we establish an "a posteriori" error estimation with two types of error indicators related to the discretization and to the linearization. Finally, numerical investigations are shown and discussed.
