Softening

Softening

[saw-fuhn, sof-uhn]
Softening is a numerical trick used in N-body techniques to prevent numerical divergences when a particle comes too close to another (and the force goes to infinity). This is obtained by modifying the gravitational potential of each particle as

Phi = - frac{1}{sqrt{r^2 + epsilon^2}}

where epsilon is the softening parameter. The value of the softening parameter should be set small enough to keep simulations realistic.
