flt FixedForceRegion::energy ( Box &  box )

inlinevirtual

Potential energy due to this Interaction.

Implements Interaction.

flt FixedForceRegion::pressure ( Box &  box )

inlinevirtual

Partial pressure due to this Interaction.

\(P = \sum_{\left<i,j \right>} \vec r_{ij} \cdot \vec F_{ij}\), or equivalently \(P = \sum_i \vec r_i \cdot \vec F_i\)

Note that the full pressure involves all interactions and temperature, and needs to be normalized by \( \frac{1}{dV} \) where \(d\) is the number of dimensions and \(V\) is the volume.

Implements Interaction.

void FixedForceRegion::set_forces ( Box &  box )

inlinevirtual

Implements Interaction.
