Abstract

We present an overview of the mesh adaptation facility of the DLR TAU code as well as details of improvements made to it in the recent MEGADESIGN project, in particular focusing on advances made in the core of the adaptation module (for example parallel (de-)refinement and other efficiency improvements) as well as a relatively new type of adaptation indicator based on the adjoint solution (among other things) for a goal-oriented mesh adaption. These improvements to the existing algorithms already available in the TAU code allow us to produce improved computational meshes in a more distributed manner, which provide more accurate predictions for selected functionals of the flow solution such as drag or lift -- in fact, for any for which the necessary adjoint solution can be computed.
