Arrows show the independently evolved M1 radiation flux. Arrows have equal length and show direction only.

Movies show saved numerical states; no applicable analytic reference is recorded.

Central z=0+ radiation energy slice with faint cell mesh and equal-length flux direction arrows. Arrows show the independently evolved M1 radiation flux. Gray density contours and a matching density/velocity panel. Synchronized gas and radiation temperature profiles along the central x line appear below the maps. Fixed color limits; actual stored Silo times held without solution interpolation. Movies show saved numerical states; no applicable analytic reference is recorded. The maps show the full simulation domain without cropping. The temperature profile also spans the full domain.
