This article presents a one-dimensional prototype for the Boltzmann equation and describes how to obtain the corresponding dual problem. The solution of the dual problem provides refinement indicators which in turn are used to improve the accuracy of finite-element approximations

We present the shape-linearized adjoint of a free-boundary problem. It is used to compute a-posteriori error estimates of goal functionals of the free-boundary-problem solution. We consider its applicability in goal-oriented adaptive mesh-refinement.@en
In this work we focus on the implications of the treatment of boundary conditions in goal-oriented error-estimation methods for fluid-structure-interaction problems. We show that two distinct formulations that appear to be equivalent for the primal problem, can behave very differ
