A differential filter applied to turbulent flows via the CG method. In the elixir the filter is integrated into Trixi through callbacks, the file support_functions_khi contains the necessary functions to run this simulation. In filter_a_posteriori we apply the filter to some test function or apply the filter a posteriori to the unfiltered solution given by Trixi. The main file calls upon all the other functions and lets you choose, which case you want to simulate. Main reference for the differential filter is:
