GRChombo: Adaptive Mesh Refinement for a Black Ring

A thin black ring (nu=0.3) in five dimensions undergoing a mix of elastic and Gregory-Laflamme instability with the mesh refinement area shown. The video is sped up such that one frame in the video corresponds to 32 time steps on the coarsest level shown (and even more on finer levels). This leads to the 'hectic' appearance of the mesh.
