This is a public dataset of metric data from a GRTeclyn binary black hole simulation.
Generated using a slightly modified version of the very cheap example parameter file.
The metric dataset contains these keys:
coords: (t,x,y,z) coordinates,levelof the adaptive mesh refinement,g_triu: the upper diagonal components of the spacetime metric
