Detailed Description

template<int DIM>
class SAMRAI::appu::EmbeddedBoundaryShapeSphere< DIM >

The user must specify in the input a "center" and a "radius". An example input entry would look like:

*        Shape1 {
*           type = "SPHERE"
*           center = 40.0 , 15.0, 15.0
*           radius = 5.0
*        }

Constructor & Destructor Documentation

◆ EmbeddedBoundaryShapeSphere()

template<int DIM>

SAMRAI::appu::EmbeddedBoundaryShapeSphere< DIM >::EmbeddedBoundaryShapeSphere	(	const std::string &	object_name,
		tbox::Pointer< tbox::Database >	input_db
	)

The constructor initializes center and radius to NaN.

Parameters

object_name	name of object of this class
input_db	the input database which contains radius and center specification.

◆ ~EmbeddedBoundaryShapeSphere()

template<int DIM>

SAMRAI::appu::EmbeddedBoundaryShapeSphere< DIM >::~EmbeddedBoundaryShapeSphere ( )

The destructor does nothing.

Member Function Documentation

◆ isInside() [1/2]

template<int DIM>

bool SAMRAI::appu::EmbeddedBoundaryShapeSphere< DIM >::isInside ( const double * xyz ) const

virtual

Concrete implementation of the isInside() method defined by the EmbeddedBoundaryShape base class. This method indicates whether the supplied xyz coordinates are inside or outside of the sphere.

Parameters

xyz	double array[DIM] specifying coordinates.

Reimplemented from SAMRAI::appu::EmbeddedBoundaryShape< DIM >.

◆ isInside() [2/2]

template<int DIM>

void SAMRAI::appu::EmbeddedBoundaryShapeSphere< DIM >::isInside	(	const int *	nx,
		const double *	dx,
		const double *	origin,
		int *	inout
	)		const

virtual

Concrete implementation of the isInside() method defined by the EmbeddedBoundaryShape base class. This method indicates whether the array of xyz coordinates are inside or outside of the sphere.

Parameters

nx	integer array [DIM] specifying number of points in each dir
dx	double array [DIM] specifying spacing of points in each dir
origin	double array [DIM] specifying origin of lower corner
inout	int array dimensioned the total number of points (i.e. nx[0]nx[1]nx[2]). This is an OUTPUT quantity.

Reimplemented from SAMRAI::appu::EmbeddedBoundaryShape< DIM >.
