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 300 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.
