Detailed Description

PeriodiCube.

A topologically periodic mesh of the unit cube into 6*n*n*n tetrahedrons, being able to export itself in the neutral *.mesh format for NETGEN, just for visualisation

Constructor & Destructor Documentation

PeriodiCube::PeriodiCube	(	uint	n,
		Real	jitter = 0
	)

Constructor.

The mesh has 6*n*n*n elements. The inner points are moved in all directions by a random value between -jitter/n and jitter/n.

Parameters:

n	mesh size
jitter	jitter parameter

virtual PeriodiCube::~PeriodiCube

(

)

[virtual]

Destructor.
