Leibniz MMS Days 2017 - Abstract
The mesh of a numerical model has a fundamental impact on the quality of the obtained discrete solution. In order to let well-calibrated turbulence closure schemes dominate the simulated mixing, the spurious mixing caused by advective transports through the mesh must be minimised. In geophysical applications vertically adaptive meshes are a promising approach to do so. In this talk different algorithms that during runtime adapt the discrete model layers to the fluid flow (in order to minimise vertical transports across the layer interfaces), to isopycnals (in order to minimise diapycnal transports along the model layers) as well as to regions where high vertical resolution is needed (in order to minimise truncation errors) are presented.
