Member Function Documentation

cutoff()

double TabulatedAngleBond::cutoff ( ) const

inline

Definition at line 93 of file bonded_tab.hpp.

energy()

double TabulatedAngleBond::energy ( Utils::Vector3d const &  vec1, Utils::Vector3d const &  vec2  ) const

inline

Compute the three-body angle interaction energy.

It is assumed that the potential is tabulated for all angles between 0 and Pi.

Parameters

[in]	vec1	Vector from central particle to left particle.
[in]	vec2	Vector from central particle to right particle.

Definition at line 200 of file bonded_tab.hpp.

forces()

std::tuple< Utils::Vector3d, Utils::Vector3d, Utils::Vector3d > TabulatedAngleBond::forces ( Utils::Vector3d const &  vec1, Utils::Vector3d const &  vec2  ) const

inline

Compute the three-body angle interaction force.

Parameters

[in]	vec1	Vector from central particle to left particle.
[in]	vec2	Vector from central particle to right particle.

Returns

Forces on the second, first and third particles, in that order.
