Abstract:
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.
