clone()

template<class real_type >

virtual aRealRefinement1d * dg::aRealRefinement1d< real_type >::clone ( ) const

pure virtual

Implemented in dg::RealIdentityRefinement< real_type >, dg::RealLinearRefinement< real_type >, dg::RealFemRefinement< real_type >, dg::RealEquidistRefinement< real_type >, and dg::RealExponentialRefinement< real_type >.

generate()

template<class real_type >

void dg::aRealRefinement1d< real_type >::generate ( const RealGrid1d< real_type > &  g_old, thrust::host_vector< real_type > &  weights, thrust::host_vector< real_type > &  abscissas  ) const

inline

Generate the grid transformation.

Parameters

g_old	The 1d grid to refine
weights	A 1d vector of size N_new. These represent the Jacobian of the transformation \[\frac{\partial \zeta}{\partial x} \] . The new metric element has thus to be multiplied by weights^2 and the volume by 1/weights
abscissas	A 1d vector of size N_new. These are the new abscissas \( x(\zeta) \) of the grid.

N_new()

template<class real_type >

unsigned dg::aRealRefinement1d< real_type >::N_new ( unsigned  N_old, bc  bcx  ) const

inline

the new number of cells

Parameters

N_old	the old number of cells
bcx	the boundary condition of the grid
