std::vector< double > const &  force 
)
inline

Definition at line 88 of file bonded_tab.hpp.

Member Function Documentation

◆ cutoff()

double TabulatedAngleBond::cutoff ( ) const
inline

Definition at line 84 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]vec1Vector from central particle to left particle.
[in]vec2Vector from central particle to right particle.

Definition at line 191 of file bonded_tab.hpp.

References calc_cosine(), and TabulatedBond::pot.

◆ 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]vec1Vector from central particle to left particle.
[in]vec2Vector from central particle to right particle.
Returns
Forces on the second, first and third particles, in that order.
