#### What is $\mathtt{grim}$ ?

$\mathtt{grim}$ is a conservative, shock-capturing code designed to solve a broad range of physical models that describe plasmas in general relativity away from local thermodynamic equilibirum. It is currently being used to study accretion flows around Kerr blackholes in order to make predictions on the emissions and spectra from SgrA*, the supermassive blackhole at the center of the Milky Way whose horizon scale will be resolved by the Event Horizon Telescope.
