### Abstract

We will present preliminary results of the direct numerical simulation of the incompressible MHD problem. The system is forced at large-scale and an external magnetic field $B_0 \hat{z}$ is applied. Anisotropy is studied in terms of the decomposition group for rotation in $3D$, the so-called $SO(3)$ group. Similarities and differences with the anisotropic pure hydrodynamical case will be discussed.
