Detailed Description

Generator of honeycomb meshes, used as starting points for many simulations.

This class takes in options such as width, height, number of ghost nodes and generates a honeycomb mesh (with equal distance between nodes), and ghost node information when requested.

NOTE: the user should delete the mesh after use to manage memory.

Constructor & Destructor Documentation

HoneycombMeshGenerator::HoneycombMeshGenerator	(	unsigned	numNodesAlongWidth,
		unsigned	numNodesAlongLength,
		unsigned	ghosts = `3`,
		bool	cylindrical = `true`,
		double	scaleFactor = `1.0`
	)

Honeycomb Mesh Generator

Parameters:

	numNodesAlongWidth	The number of cells you want alopng the bottom of the domain,
	numNodesAlongLength	The number of cells you want sides of the domain,
	ghosts	The thickness of ghost nodes to put around the edge (defaults to 3),
	cylindrical	Whether the mesh should be cylindrically periodic (defaults to true),
	scaleFactor	The scale factor for the width (circumference) of the cells.
