sarkas.potentials.force_pm.calc_mesh_coord(pos, h_array, cao)[source]#

Calculate the particles positions with respect to the mesh and their closest point on the mesh.

Parameters

  • pos (numpy.ndarray) – Particles’ positions.

  • h_array (numpy.ndarray) – Width of the mesh cells.

  • cao (numpy.ndarray) – Charge assignment order.

Returns

  • mesh_pos (numpy.ndarray) – Particles’ positions relative to the mesh, i.e. pos/h_array.

  • mesh_points (numpy.ndarray) – Particles’ positions on the mesh.
