conf.plot.grid_boundary not defined

[Jerrypiglet]

conf.plot.grid_boundary (code here) is not defined in any of the provided config files. Shall I set it to grid_boundary = [-1.1, 1.1]?

Sorry for my mistake, I'll update the config file.
Considering that the scene is bounded by a sphere with radius 3, I think setting grid_boundary to [-1.5, 1.5] (my choice) or [-2.0, 2.0] is suitable. A too small grid_boundary will lead to incomplete mesh, while too large will lose mesh details due to the limited resolution in marching cubes.
