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.
Immersed finite element methods generally suffer from conditioning problems when cut elements intersect the physical domain only on a small fraction of their volume. De Prenter et al. [Computer Methods in Applied Mechanics and Engineering, 316 (2017) pp. 297–327] present an analysis for symmetric positive definite (SPD) immersed problems, and for this class(More)
