Detailed Description

\( \sqrt{g} \)

Function Documentation

inv_volume()

template<class Geometry >

get_host_vector< Geometry > dg::create::inv_volume

(

const Geometry &

g

)

Create the inverse volume element on the grid (including weights!!)

This is the same as the inv_weights divided by the volume form \( \sqrt{g}\)

Template Parameters

Geometry

A type that is or derives from one of the abstract geometry base classes ( aGeometry2d, aGeometry3d, aMPIGeometry2d, ...).

Parameters

g	Geometry object

Returns

The inverse volume form

volume()

template<class Geometry >

get_host_vector< Geometry > dg::create::volume

(

const Geometry &

g

)

Create the volume element on the grid (including weights!!)

This is the same as the weights multiplied by the volume form \( \sqrt{g}\)

Template Parameters

Geometry

A type that is or derives from one of the abstract geometry base classes ( aGeometry2d, aGeometry3d, aMPIGeometry2d, ...).

Parameters

g	Geometry object

Returns

The volume form
