Member Function Documentation

void SoftWall::add ( WallAtom  a )

inline

flt SoftWall::energy ( Box &  box )

virtual

Potential energy due to this Interaction.

Implements Interaction.

flt SoftWall::get_last_f ( )

inline

Vec SoftWall::get_location ( )

inline

Vec SoftWall::get_normal ( )

inline

flt SoftWall::pressure ( Box &  box )

virtual

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 SoftWall::set_forces ( Box &  box )

virtual

Implements Interaction.

flt SoftWall::set_forces_get_pressure ( Box &  box )

virtual

Set forces (Atom.f) and return \(P = \sum_{\left<i,j \right>} \vec r_{ij} \cdot \vec F_{ij}\) at the same time (see pressure()).

Reimplemented from Interaction.

void SoftWall::set_location ( Vec  newloc )

void SoftWall::set_normal ( Vec  newNorm )
