Towards an Output-based Re-meshing for Turbomachinery Applications

<p>The truncation error estimation methodology using topologically inconsistent fine and coarse meshes was<br> presented. Estimated truncation error was weighted with an adjoint solution to obtain a robust output-based adaptation<br> sensor.<br> Re-meshing using Boxer and output-based sensor field was successfully applied to the simple cube test case showing<br> almost an order of magnitude cost function error reduction as compared to the uniformly refined grid.<br> More application examples are required including a more realistic turbulent cases e.g. turbine stator in order to investigate how useful is the methodology in practice.<br> The key challenge for viscous flows is related to the treatment of boundary layer when performing re-meshing with Boxer
