Member Function Documentation

calc_charges()

void scal_fmm::fmm::calc_charges ( std::function< const Eigen::Vector3d(Nodes::Node)>  getter, Mesh::mesh &  msh  )

inlineprivate

computes all charges from tetraedrons and facettes for the demag field to feed a tree in the fast multipole algo (scalfmm)

calc_demag()

void scal_fmm::fmm::calc_demag ( Mesh::mesh &  msh )

inline

launch the calculation of the demag field with second order corrections

Parameters

[in]

msh

demag()

void scal_fmm::fmm::demag ( std::function< const Eigen::Vector3d(Nodes::Node)>  getter, std::function< void(Nodes::Node &, const double)>  setter, Mesh::mesh &  msh  )

inlineprivate

computes the demag field, with (getter = u,setter = phi) or (getter = v,setter = phi_v)

insertCharges()

template<class T , const int NPI>

void scal_fmm::fmm::insertCharges ( std::vector< T > const &  container, FSize &  idx, Eigen::Ref< Eigen::Vector3d > const  c  )

inlineprivate

function template to insert volume or surface charges in tree for demag computation. class T is Tet or Fac, it must have getPtGauss() method, second template parameter is NPI of the namespace containing class T
