Disk-averaged quantities in the 2D validation runs. Disk-averaged quantities in the 2D validation runs. The blue curves are obtained with BHAC and the red curves with HARM3D in a two-dimensional setting. The shaded regions mark the 1σ standard deviation of the spatially-averaged snapshots (omitted for the highly fluctuating \(\langle\beta\rangle\)). Apart from a slightly higher magnetisation in HARM for \(r\in[20,30]\), we find excellent agreement between both codes.
