47 results about "Softening" patented technology

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 Φ=-1/(√(r²+ε²)), where ε is the softening parameter. The value of the softening parameter should be set small enough to keep simulations realistic.
