Example parameter files for Trixi

This folder contains parameter files that can be used to just try out Trixi and that also serve as a starting point to create new simulation setups. Furthermore, these files are also the basis for our automated Trixi tests and each new file put in here should be added either to the basic or the extended test set in ../test/test_examples.jl.

There are also a few files that were configured such that they lend themselves to doing convergence tests with convtest, i.e., to determine the experimental order of convergence (EOC):

• parameters.toml: EOC tests for linear scalar advection with polydeg = 3.
• parameters_source_terms.toml: EOC tests for Euler equations with polydeg = 3.
• parameters_alfven_wave.toml: EOC tests for MHD equations with polydeg = 3.
• parameters_hyp_diff_llf.toml: EOC tests for hyperbolic diffusion equations with polydeg = 4.

In general, a good first parameter file to try out as a new user is parameters.toml, as it is short, takes less than a second to run, and uses only the basic features of Trixi.
