A Posteriori Error Estimates for Darcy–Forchheimer’s Problem
Computational Methods in Applied Mathematics, 2022 Abstract This work deals with the a posteriori error estimates for the Darcy–Forchheimer problem. We first introduce the corresponding variational formulation for the nonlinear problem and discretize it by using the finite-element method.

Neural network guided adjoint computations in dual weighted residual error estimation
SN Applied Sciences, 2022 In this work, we are concerned with neural network guided goal-oriented a posteriori error estimation and adaptivity using the dual weighted residual method. The primal problem is solved using classical Galerkin finite elements.

A posteriori analysis of the spectral element discretization of a non linear heat equation
Advances in Nonlinear Analysis, 2020 The paper deals with a posteriori analysis of the spectral element discretization of a non linear heat equation. The discretization is based on Euler’s backward scheme in time and spectral discretization in space. Residual error indicators related to the

A Posteriori Estimation of Dimension Reduction Errors [PDF]
, 2004 A new a posteriori error estimator is presented for the verification of the dimensionally reduced models stemming from the elliptic problems on thin domains. The original problem is considered in a general setting, without any specific assumptions on the domain geometry, coefficients and the right-hand sides.

Reservoir Simulator Runtime Enhancement Based on a Posteriori Error Estimation Techniques
Oil & Gas Science and Technology, 2016 In this work, we show how the a posteriori error estimation techniques proposed in [Di Pietro et al. (2014) Computers & Mathematics with Applications 68, 2331-2347] can be efficiently employed to improve the performance of a compositional reservoir ...
