Grid-Adaptation for Wall-Modeled Large Eddy Simulation Using Unstructured High-Order Methods
Please login to view abstract download link
The accuracy and computational cost of a large eddy simulation (LES) are highly dependent on the computational grid. Building optimal grids manually from a priori knowledge is not feasible in most practical use cases; instead, solution-adaptive strategies can provide a robust and cost-efficient method to generate a grid with the desired accuracy. We adapt the grid-adaptation algorithm developed by Toosi and Larsson to the Discontinuous Galerkin Spectral Elements Method (DGSEM) framework FLEXI and show its potential on fully unstructured grids.
