[Users] error after activating IllinoisGRMHD and VolumeIntegrals_GRMHD

[Zach Etienne]

Hi Chia-Hui,

If you really want to use VolumeIntegrals_GRMHD, you are more than welcome
to do so. However, the parameter file you are using from the examples
gallery will need to be significantly modified to be compatible with
IllinoisGRMHD. My immediate thought (which may be correct or incorrect) is
that it is attempting to initialize both GRHydro and IllinoisGRMHD
simultaneously.

If you want to use IllinoisGRMHD, the easiest route would be to start with
a parameter file in the following wvuthorns_diagnostics directory:
https://bitbucket.org/zach_etienne/wvuthorns_diagnostics/src/master/Meudon_Bin_NS-modified/par/

I haven't had time yet to fully set up a gallery example for this BNS case,
so beware: you may need to modify the parameter file a bit to make it work
properly. I'm hoping to schedule the next IllinoisGRMHD Working Group
telecon in the next few weeks, so please stay tuned if you are interested.

-Zach
