We present an output-based mesh adaptation strategy for Navier-Stokes simulations on deforming domains. The equations are solved with an arbitrary Lagrangian-Eulerian (ALE) approach, using a discontinuous Galerkin finiteelement discretization in both space and time. Discrete unsteady adjoint solutions, derived for both the state and the geometric(More)
This paper presents a novel approach to solution-based adaptation for unsteady discretizations of symmetrizable conservation laws. This approach is based on an extension of the entropy adjoint approach, which was previously introduced for steady-state simulations. Key to the approach is the interpretation of symmetrizing entropy variables as adjoint(More)
We present an output-based adaptation strategy for high-order simulations of the compressible Navier-Stokes equations on deformable domains. The equations are solved on a mapped reference domain using an arbitrary Lagrangian-Eulerian approach. The discretization is a discontinuous Galerkin finite-element method in space and time. Discrete unsteady adjoint(More)
