Comment (by Peter Diener):

The code compiled okay, but I have trouble running the Balsara1 tests in GRHayLHD and GRHayLMHD. First of all both tests tried to set a parameter from GRHayLID called test_1D_initial_data. However, the parameter defined there is initial_data_1D. In addition they tried to set test_shock_direction, whereas the parameter defined in GRHayLID is shock_direction.After fixing those, the tests started running but failed when trying to do output of GRHayLHD::rho_b and GRHayLHD::pressure (similarly for GRHayLMHD). Looking in the interface.ccl of the hydro thorns is see rho_b and pressure mentioned in a comment but they are not defined.
