Detailed Description

This module contains the definition of a polygon and some related subroutines

Attention

Modify these functions at your own risk. Many algorithms depend on the specific behaviour of these functions. They are designed to not generate false negative results. Note that false positive results may occur due to the finite representation of real numbers. Take that into consideration when writing new algorithms.

Function/Subroutine Documentation

cg2_axisym_polygon_centroid()

pure subroutine mod_cg2_axisym_polygon::cg2_axisym_polygon_centroid	(	type(t_polygon), intent(in)	polygon,
		double precision, dimension(2), intent(out)	centroid,
		double precision, intent(out), optional	volume )

Compute the centroid of a polygon.

This routine computes the coordinates of the centroid and the volume of a polygon in axisymmetric configuration.

Parameters

[in]	polygon	Any polygon
[out]	centroid	Centroid of the polygon
[out]	volume	Volume of the polygon

(

type(t_polygon), intent(in)

polygon

)

Compute the area of a polygon.

Parameters

[in]

polygon

Any polygon
