We present the turbulent and thermal evolution of a magnetized protoplanetary disks using full global 3D radiative MHD simulations including frequency dependent irradiation by the star. We perform classical 2D radiative viscous disk simulations to compare with the full model. The temperature evolution differs significantly between the two models, mainly due to the non uniform heating in case of the magneto rotational instability (MRI). In the full 3D model, the midplane temperature is flat and determined by the disk infrared surface temperature. The classical viscous models show the expected peak at the midplane due to the assumption of constant accretion stress. During the development of our method we focused on serial and parallel performance. As a result our method present high computational efficiency and we reach parallel scaling up to 70% using 1024 cpu’s.
