Recent Developments of TAU Adaptation Capability

Abstract

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