[FLASH-USERS] Question on RiemannSolver in the parfile

[Ryan Farber]

Hybrid switches between HLLC and X for hydro and HLLD and X for MHD.

I forget exactly if it switches to LLF or HLL but you can check (and modify as desired) in the source code (possibly hy_uhd_unsplit otherwise one of the subroutines therein).
