Return a Grid with the same number of orbitals along each dimension with the specified Wigner-Seitz radius.

dimension int

The number of spatial dimensions.

grid_length int

The number of orbitals along each dimension.

wigner_seitz_radius float

The Wigner-Seitz radius per particle, in Bohr.

filling_fraction float

The average spin-orbital occupation. Specifies the number of particles (rounding down).

spinless boolean

Whether to give the system without or with spin.
