TABLE II.
Grid structure for all cases listed in Table I. The computational mesh consists of one set of j-nested AMR grids centered at the start, in which equatorial symmetry is imposed. Here j = 5, …, levelmax denotes the number of AMR grids during a given evolution epoch, and levelmax is the maximum number of AMR grids at the end of the simulations. Each case begins with a set of j = 5-AMR grids, and we add a new refinement level every time the maximum value of the rest-mass density increases by a factor of three. The finest level for a given set of j-nested grids is denoted by Δxmin. The grid spacing of all other levels is 2l−1Δxmin, where l = 1, …, j, is the level number such that l = 1 corresponds to the coarsest level. The half-side length of the outermost AMR boundary is given by the first number in the grid hierarchy.
