sarkas.potentials.yukawa.yukawa_force#

sarkas.potentials.yukawa.yukawa_force(r_in, pot_matrix)[source]#

Numba’d function to calculate Potential and Force between two particles.

Parameters

  • r_in (float) – Distance between two particles.

  • pot_matrix (numpy.ndarray) – It contains potential dependent variables.

    Shape = (3, sarkas.core.Parameters.num_species, sarkas.core.Parameters.num_species)

Returns

  • u_r (float) – Potential.

  • f_r (float) – Force between two particles.

Examples

>>> import numpy as np
>>> r = 2.0
>>> pot_matrix = np.array([ 1.0, 1.0, 0.0001])
>>> yukawa_force(r, pot_matrix)
