Detailed Description

template<class real_type>
struct dg::geo::aRealGeneratorX2d< real_type >

The abstract generator base class.

A generator is there to construct coordinate transformations from physical coordinates \( x,y\) to the computational domain \(\zeta, \eta\), which is a product space.

Note

the origin of the computational space is assumed to be (0,0)

virtual aRealGeneratorX2d * dg::geo::aRealGeneratorX2d< real_type >::clone ( ) const

pure virtual

Abstract clone method that returns a copy on the heap.

Returns

a copy of *this on the heap

Implemented in dg::geo::RibeiroX, and dg::geo::SeparatrixOrthogonal.

Generate grid points and elements of the Jacobian.

Parameters

zeta1d	(input) a list of \( N_\zeta\) points \( 0<\zeta_i<\)width()
eta1d	(input) a list of \( N_\eta\) points \( 0<\eta_j<\)height()
nodeX0	is the index of the first point in eta1d after the first jump in topology in \( \eta\)
nodeX1	is the index of the first point in eta1d after the second jump in topology in \( \eta\)
x	(output) the list of \( N_\eta N_\zeta\) coordinates \( x(\zeta_i, \eta_j)\)
y	(output) the list of \( N_\eta N_\zeta\) coordinates \( y(\zeta_i, \eta_j)\)
zetaX	(output) the list of \( N_\eta N_\zeta\) elements \( \partial\zeta/\partial x (\zeta_i, \eta_j)\)
zetaY	(output) the list of \( N_\eta N_\zeta\) elements \( \partial\zeta/\partial y (\zeta_i, \eta_j)\)
etaX	(output) the list of \( N_\eta N_\zeta\) elements \( \partial\eta/\partial x (\zeta_i, \eta_j)\)
etaY	(output) the list of \( N_\eta N_\zeta\) elements \( \partial\eta/\partial y (\zeta_i, \eta_j)\)

Note

the first ( \( \zeta\)) coordinate shall be constructed contiguously in memory, i.e. the resuling lists are \( x_0=x(\zeta_0, \eta_0),\ x_1=x(\zeta_1, \eta_0)\ x_2=x(\zeta_2, \eta_0)\dots x_{NM-1}=x(\zeta_{N-1} \eta_{M-1})\)

All the resulting vectors are write-only and get properly resized
