Detailed Description

template<class real_type>
struct dg::geo::RealCurvilinearGrid2d< real_type >

A two-dimensional grid based on curvilinear coordinates.

Constructor & Destructor Documentation

RealCurvilinearGrid2d() [1/3]

template<class real_type >

dg::geo::RealCurvilinearGrid2d< real_type >::RealCurvilinearGrid2d ( const aRealGenerator2d< real_type > &  generator, unsigned  n, unsigned  Nx, unsigned  Ny, dg::bc  bcx = dg::DIR, bc  bcy = dg::PER  )

inline

Construct a 2D grid.

the coordinates of the computational space are called x,y

Parameters

generator	generate the grid: the grid boundaries are [0, generator.width()] x [0, generator.height()]
n	number of Gaussian nodes in x and y (1<=n<=20 )
Nx	number of cells in x
Ny	number of cells in y
bcx	boundary condition in x
bcy	boundary condition in y
