espressopp.interaction.GravityTruncated

This is an implementation of a truncated (cutoff) Gravity Potential

\[U = P \cdot \frac{m_1 \cdot m_2}{ \lvert p_1 - p_2\rvert}\]

where \(m_i\) is the mass of the i th particle, \(p_i\) its position and P a prefactor.

espressopp.interaction.GravityTruncated(prefactor, cutoff)

Parameters:

• prefactor (real) – (default: 1.0)
• cutoff – (default: infinity)
