| Abstract: | We present 3D simulations of a system of four neutral clumps embedded in a photoionized region. In this system, we have three small clumps which partially shield a single, larger clump from the stellar ionizing photons. This flow evolves to form a neutral structure with a main body and three neutral 'columns' pointing towards the central star. Qualitatively, similar structures are seen in the 'Finger' of the Carina Nebula. |
