Detailed Description

An abstract class for the initialization of the geometry of fluid objects.

This class can be used as a function object: the operator() is overloaded as the level set function of particle geometry

Member Function Documentation

virtual void Geometry::getBoundingBox ( double &  xmin, double &  xmax, double &  ymin, double &  ymax, double &  zmin, double &  zmax  )

pure virtual

Calculates the bounding box of a geometric shape.

For example, for a ball in 3D with center (xcen, ycen, zcen) and radius r the bounding box is calculated as ([xcen-r,xcen+r],[ycen-r,ycen+r],[zcen-r,zcen+r])

Parameters

[out]	xmin	The minimum in x-coordinate
[out]	xmax	The maximum in x-coordinate
[out]	ymin	The minimum in y-coordinate
[out]	ymax	The maximum in y-coordinate
[out]	zmin	The minimum in z-coordinate
[out]	zmax	The maximum in z-coordinate

Returns

None

Implemented in Disk, DiskRight, Ball, DiskLeft, and Line.

virtual bool Geometry::operator() ( double  x, double  y, double  z  ) const

pure virtual

Level set function of particle geometry.

Parameters

[in]	x	The x-coordinate
[in]	y	The y-coordinate
[in]	z	The z-coordinate

Returns

true if (x,y,z) is inside the level set function; false otherwise

Implemented in Disk, DiskRight, Ball, DiskLeft, and Line.
