Profile along the x-axis of various physical quantities of the model at three different times: t/t_ff = 0.1, 0.5 and 1.0. (a) density ρ, (b) temperature T, (c) x-component of the velocity υ_x, (d) total velocity magnitude |v|, (e) y-component of magnetic field B_y, (f) Mach number ℳ, (g) total magnetic field |B| magnitude, (h) mass flux , (i) ambipolar diffusion resistivity coefficient η_AD, and (j) abundance e⁻/H₂. The solid lines correspond to non-ideal MHD, dashed lines to ideal MHD. The gray area in the middle corresponds to 0.1 pc to guide the reader to identify the typical width of the filaments. We note that in panel (j), in the ideal case (dashed lines), η_AD is reported for the sake of comparison, but it is not included in the MHD equations.
