Detailed Description

template<int dim, int spacedim = dim>
class CylindricalManifold< dim, spacedim >

Cylindrical Manifold description. In three dimensions, points are transformed using a cylindrical coordinate system along the x-, y- or z-axis (when using the first constructor of this class), or an arbitrarily oriented cylinder described by the direction of its axis and a point located on the axis.

This class was developed to be used in conjunction with the cylinder or cylinder_shell functions of GridGenerator. This function will throw an exception whenever spacedim is not equal to three.

Constructor & Destructor Documentation

CylindricalManifold() [1/2]

template<int dim, int spacedim>

CylindricalManifold< dim, spacedim >::CylindricalManifold	(	const unsigned int	axis = 0,
		const double	tolerance = 1e-10
	)

Constructor. Using default values for the constructor arguments yields a cylinder along the x-axis (axis=0). Choose axis=1 or axis=2 for a tube along the y- or z-axis, respectively. The tolerance value is used to determine if a point is on the axis.

Definition at line 139 of file manifold_lib.cc.

CylindricalManifold() [2/2]

template<int dim, int spacedim>

CylindricalManifold< dim, spacedim >::CylindricalManifold	(	const Point< spacedim > &	direction,
		const Point< spacedim > &	point_on_axis,
		const double	tolerance = 1e-10
	)

Constructor. If constructed with this constructor, the manifold described is a cylinder with an axis that points in direction direction and goes through the given point_on_axis. The direction may be arbitrarily scaled, and the given point may be any point on the axis. The tolerance value is used to determine if a point is on the axis.
