sarkas.potentials.force_pm.calc_acc_pm(E_x_r, E_y_r, E_z_r, mesh_pos, mesh_points, q_over_m, cao, mesh_sz, mid, pshift)[source]#

Calculates the long range part of particles’ accelerations.

Parameters

  • E_x_r (numpy.ndarray) – Electric field along x-axis.

  • E_y_r (numpy.ndarray) – Electric field along y-axis.

  • E_z_r (numpy.ndarray) – Electric field along z-axis.

  • mesh_pos (numpy.ndarray) – Particles’ positions relative to the mesh.

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

  • q_over_m (numpy.ndarray) – Particles’ charges divided by their masses.

  • cao (int) – Charge assignment order.

  • mesh_sz (numpy.ndarray) – Mesh points per direction.

  • mid (numpy.ndarray) – Midpoint flag for the three directions.

  • pshift (numpy.ndarray) – Midpoint shift in each direction.

Returns

acc (numpy.ndarray) – Acceleration from Electric Field.
