Detailed Description

Perturber class for AR integration.

Member Typedef Documentation

NB

typedef H4::Neighbor<PtclHard> ARPerturber::NB

Constructor & Destructor Documentation

ARPerturber()

ARPerturber::ARPerturber ( )

inline

minimum soft perturbation

Member Function Documentation

calcSoftPertMin()

template<class Tptcl >

void ARPerturber::calcSoftPertMin ( const AR::BinaryTree< Tptcl > &  _bin, const Float  _G  )

inline

calculate soft_pert_min for slowdown pert_out

\Delta F = G m_cm m_p (apo) / rp^3 Pert_out = \Delta F /(G apo)

Parameters

[in]	_bin	binary parameters
[in]	_G	gravitatioal constant

Here is the call graph for this function:

checkParams()

bool ARPerturber::checkParams ( )

inline

check parameters status

clear()

void ARPerturber::clear ( )

inline

clear function

findCloseSoftPert()

PS::S32 ARPerturber::findCloseSoftPert ( TidalTensor *  _tt, int &  _n_tt, const int  _n_max, const H4::ParticleH4< PtclHard > &  _cm, const PS::F64  _gid  )

inline

find close tidal tensor and if (-) tensor group id is the same as input, initial tidal tensor c.m.

if the tidal tensor is already in used (group_id>=0), copy a new one after _n_tt

Parameters

[in,out]	_tt	tensor array
[in,out]	_n_tt	number of current tensor
[in]	_n_max	maximum size of tensor array
[in]	_cm	c.m. particle
[in]	_gid	group id (not necessary integer)

Returns

the tidal tensor index, if no match, return -1
