Radial stratification (away from the star) of the wind clumping factor fcl for the reference model in different dimensions. The solid curve is a 1D simulation with as found in the literature so far (but now computed with MPI-AMRVAC), while the dashed curve shows a comparable 2D simulation with . The dotted curve displays our novel 2D simulation with . The stratification curves from the 2D models appear smoother because they are laterally averaged to retrieve a single radial stratification for comparison with a purely 1D model.
