Research has been conducted using a suite of modeling codes to study LLAGN accretion disks, specifically for Sagittarius A* and M87's core. These include a GRMHD accretion flow evolver, Monte Carlo radiation transport code, and localized shearing box simulations. Modifications to these codes will be discussed, which make them particularly applicable to these types of sources. Results of interest regarding large scale flaring mechanisms in AGN disks, as well as kinetic scale particle heating methods, will be discussed and analyzed. Specifically, we cite global density changes due to mass accretion rate variations as the likely source of LLAGN flaring behavior, while double-Maxwellian electron distributions heated by magnetic reconnection may explain the high energy emissions of these accretion disks.
