A distanze interatomiche o intermolecolari molto piccole le densità elettroniche si sovrappongono generando forze repulsive molto intense, caratterizzate da un raggio d'azione molto corto e dal fatto che crescono rapidamente all'avvicinarsi So it only makes sense to take the second-order term of the Taylor expansion of the Lennard Jones potential evaluated around the potential minimum. Here's a post that shows how to arrive at the minimum of the Lennard-Jones potential for n=6: Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. But note that for Lennard-Jones interactions these errors are usually smaller than other errors, such as integration errors at the repulsive part of the potential. For Coulomb interactions we advise against using a shifted potential and for use of a reaction field or a proper long-range method such as PME. Non-bonded: Lennard-Jones or Buckingham, and Coulomb or modified Coulomb. The non-bonded interactions are computed on the basis of a neighbor list (a list of non-bonded atoms within a certain radius), in which exclusions are already removed.

The code (C language) is about molecular dynamics using the potential of Lennard Jones. The code is 100% working but I want to understand certain details: 1) why on line 67 appears 1.0e-6? 2) Why add fij.dx to index i? Why is it subtracted fij.dx from index j (lines 142 to 147)?

The Lennard-Jones 12-6 pair potential is commonly used to describe the interaction between simple molecules or atoms and it has been widely used in previous molecular simulations for both fluid-fluid and fluid-carbon interactions.

El potencial de Lennard-Jones es una aproximación. La forma del término que describe la repulsión no tiene ninguna justificación teórica; la fuerza repulsiva debe depender exponencialmente de la distancia, pero el término de la fórmula de L-J es más conveniente debido a la facilidad y eficiencia de calcular r 12 como el cuadrado de r 6.
