Detailed Description

template<int dim>
class TorusManifold< dim >

Manifold description for the surface of a Torus in three dimensions. The Torus is assumed to be in the x-z plane. The reference coordinate system is given by the angle \(phi\) around the y axis, the angle \(theta\) around the centerline of the torus, and the distance to the centerline \(w\) (between 0 and 1).

This class was developed to be used in conjunction with GridGenerator::torus.

Constructor & Destructor Documentation

TorusManifold()

template<int dim>

TorusManifold< dim >::TorusManifold	(	const double	R,
		const double	r
	)

Constructor. Specify the radius of the centerline R and the radius of the torus itself (r). The variables have the same meaning as the parameters in GridGenerator::torus().
