We model the core helium flash in a low-mass red giant using Djehuty, a fullythree-dimensional (3D) code. The 3D structures were generated from convergedmodels obtained during the 1D evolutionary calculation of a 1$\Msun$ star.Independently of which starting point we adopted, we found that after sometransient relaxation the 3D model settled down with a briskly convectingHe-burning shell that was not very different from what the 1D model predicted.Comment: 32 pages, 13 figures, accepted by ApJ. Figures reduced from high-res  eps to low-res gif for rapid download. Contact Lattanzio for a copy of the  higher res images (included, inplace, in the manuscript
