sarkas.potentials.force_pm.create_k_arrays(mesh_sizes, non_zero_box_lengths)[source]#

Calculate the reciprocal space arrays.

Parameters

  • non_zero_box_lengths (numpy.ndarray) – Length of simulation’s box in each direction. Note that no element should be equal to 0.0. If the dimensionality of the problem is lower than 3, then use 1.0 as the box length for those dimensions. Example: 2D non_zero_box_lengths = [Lx, Ly, 1.0].

  • mesh_sizes (numpy.ndarray) – Number of mesh points in x,y,z.

Returns

  • kx_v (numpy.ndarray) – Array of reciprocal space vectors along the x-axis

  • ky_v (numpy.ndarray) – Array of reciprocal space vectors along the y-axis

  • kz_v (numpy.ndarray) – Array of reciprocal space vectors along the z-axis
