The Grid class

The Grid class is an object that stores all the details of the numerical grid, such as the number of grid points, grid spacings etc.

Constructing a Grid object

A Grid object is constructed using the constructor

Grid(points, grid_spacings)

An object representing the numerical grid.

The parameter points represents the number of points in each spatial dimension. For 1D systems, this is simply an integer specifying the number of points. For dimensions equal to 2 or more, this is a tuple \((N_x, N_y)\) or \((N_x, N_y, N_z)\) representing the points in the \(x\), \(y\) and \(z\) directions, respectively.

Similarly, grid_spacings represents the numerical spacing between points for each spatial dimension.
