Constructor & Destructor Documentation

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

Constructor.

The mesh has 2*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 PeriodicSquare::~PeriodicSquare

(

)

[virtual]

Destructor.
