espressopp.standard_system.LennardJones

espressopp.standard_system.LennardJones(num_particles, box, rc, skin, dt, epsilon, sigma, shift, temperature, xyzfilename, xyzrfilename)

Parameters:

• num_particles –
• box – (default: (000))
• rc (real) – (default: 1.12246)
• skin (real) – (default: 0.3)
• dt (real) – (default: 0.005)
• epsilon (real) – (default: 1.0)
• sigma (real) – (default: 1.0)
• shift – (default: ‘auto’)
• temperature – (default: None)
• xyzfilename – (default: None)
• xyzrfilename – (default: None)

return random Lennard Jones system and integrator: if tempearture is != None then Langevin thermostat is set to temperature (gamma is 1.0)
