Detailed Description

The library of computational domains that can be selected with the run time parameter "geometry", together with the helper classes they use (include/ryujin/geometries).

Typedef Documentation

GeometryLibrary

template<int dim>

using ryujin::GeometryLibrary = typedef Library<Geometry<dim>, const std::string &>

The library of geometries: a registry of all geometries that the Discretization can select by name. The built-in geometries of the namespace Geometries are registered by default. A client adds a geometry of its own with

GeometryLibrary<dim>::add<MyGeometry<dim>>();

Definition at line 29 of file geometry_library.h.

Function Documentation

annulus()

template<int dim, int spacedim, template< int, int > class Triangulation>

void ryujin::GridGenerator::annulus	(	Triangulation< dim, spacedim > &	,
		const double	,
		const double	,
		const double	,
		const double
	)

Create a 2D/3D partial annulus configuration with the given length, height, radii and angle coverage.

We set slip boundary conditions on all boundaries.

cylinder()

template<int dim, int spacedim, template< int, int > class Triangulation>

void ryujin::GridGenerator::cylinder	(	Triangulation< dim, spacedim > &	,
		const double	,
		const double	,
		const double	,
		const double
	)

Create a 2D/3D cylinder configuration with the given length and height.

We set Dirichlet boundary conditions on the left boundary and do-nothing boundary conditions on the right boundary. All other boundaries (including the cylinder) have slip boundary conditions prescribed.

The 3D mesh is created by extruding the 2D mesh with a width equal to the "height".

step()

template<int dim, template< int, int > class Triangulation>

void ryujin::GridGenerator::step	(	Triangulation< dim, dim > &	,
		const double	,
		const double	,
		const double	,
		const double
	)

Create the 2D mach step triangulation.

Even though this function has a template parameter dim, it is only implemented for dimension 2.

wavetank()

template<int dim, int spacedim, template< int, int > class Triangulation>

void ryujin::GridGenerator::wavetank	(	Triangulation< dim, spacedim > &	,
		const double	,
		const double	,
		const double	,
		const double
	)

Create a 2D numerical wave tank with specifications outlined in Figure 4 of [18]. The tank consists of a rectangular water reservoir with a long flume attached to the "center" of the reservoir. For the sake of simplicity, we assume the centerline of the flume and reservoir align at y = 0.

All outer walls have "slip" boundary conditions except outer wall at the end of the tank which has dynamic outflow conditions.

twotanks()

template<int dim, int spacedim, template< int, int > class Triangulation>

void ryujin::GridGenerator::twotanks	(	Triangulation< dim, spacedim > &	,
		const double	,
		const double	,
		const double	,
		const double	,
		const unsigned int
	)

Create a 2D numerical tank configuration.

The domain consists of two "tanks" attached via a "tunnel". For the sake of simplicity, we assume a couple of things:

1. the two tanks are the same size,
2. the centerline of tanks and tunnel align at y = 0.

The walls of the tunnel have "slip" (or wall / reflecting) boundary conditions. The "inner" walls also have slip boundary conditions. For the left/right external boundaries, we assume "dynamic".

NOTE: The default parameters are arbitrary.

wall()

template<int dim, int spacedim, template< int, int > class Triangulation>

void ryujin::GridGenerator::wall	(	Triangulation< dim, spacedim > &	,
		const double	,
		const double	,
		const double
	)

Create a 2D double-mach reflection wall configuration:

A rectangular domain with given length and height. The boundary conditions are dirichlet conditions on the top and left of the domain and do-nothing on the right side and the front part of the bottom side from [0, wall_position). Slip boundary conditions are enforced on the bottom side on [wall_position, length).
