inline

constructor, initialize memory for tree, kernel, sources corrections, initialize all sources

Parameters

[in]	msh
[in]	prmTet
[in]	prmTri
[in]	ScalfmmNbThreads

Member Function Documentation

calc_charges()

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

inlineprivate

computes all charges from tetraedrons and triangles 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

Compute the demagnetizing field. Include the second order corrections if FIRST_ORDER=OFF (which is the default).

Parameters

[in]

msh

demag()

void scal_fmm::fmm::demag ( const std::function< const Eigen::Vector3d(const Nodes::Node &)> &  getter, const 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 ( const std::vector< T > &  container, const std::vector< int > &  idxContainer, FSize &  idx, const Eigen::Ref< const Eigen::Vector3d >  c  )

inlineprivate

function template to insert volume or surface charges in tree for demag computation. class T is Tet or Tri, it must have getPtGauss() method to get the Gauss points, second template parameter is NPI of the namespace containing class T. idxContainer is the list of indices of the magnetic T elements stored in container.
