The matter orbiting around black hole in microquasar or active galactic nuclei forms toroidal accretion disk structures. The main topic of this talk will be general relativistic magnetohydrodynamics (GRMHD) simulations of multiple accretion configurations orbiting around one central black hole. Such structures have been recently described as ringed accretion disks (RADs) in full general relativistic approach. With the use of GRMHD numerical code HARM-COOL the RAD configurations time evaluations will be modeled and RAD stability will be tested. To boost interactions between individual rings from RAD configuration, large scale magnetic filed will be added into RAD model. Accretion configurations with different distribution of angular momentum inside will be also compared.
