Distribution of the relative angle between the filament crests and the radial direction from the centre of the cloud in simulations High_B (top row) and Low_B (bottom row). The black dashed lines mark the random distribution for the relative orientation of two independent vectors in 3D. The distributions evolve similarly for both cases, but Low_B filaments display a more pronounced preference towards radial alignment from early stages due to the strong influence of the central potential well. As High_B develops a central hub (at SFE = 6%), a similar radial configuration arises.
