Abstract: This paper investigates the a posteriori error estimates associated with the Darcy–Forchheimer problem under pressure boundary conditions. The problem is discretized using finite element methods and an iterative scheme is recalled along with its corresponding convergence properties. We then derive a posteriori error estimates, where the error between the exact and approximate solutions is bounded by two types of indicators: one related to the discretization and the other to the iteration process. Finally, we present several numerical experiments using the adaptive mesh method to highlight the effectiveness of the proposed approach.
