Neural network guided adjoint computations in dual weighted residual error estimation

Roth, Julian; Schröder, Max; Wick, Thomas ([Cham] : Springer International Publishing, 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 ...
Numerical Modeling and Open-Source Implementation of Variational Partition-of-Unity Localizations of Space-Time Dual-Weighted Residual Estimators for Parabolic Problems

Thiele, J.P.; Wick, T. (New York, NY [u.a.] : Springer Science + Business Media B.V., 2024)

In this work, we consider space-time goal-oriented a posteriori error estimation for parabolic problems. Temporal and spatial discretizations are based on Galerkin finite elements of continuous and discontinuous type. The ...
