Detailed Description

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
class TrianglesMeshReader< ELEMENT_DIM, SPACE_DIM >

Concrete version of the AbstractCachedMeshReader class. Once constructed the public methods of the AbstractCachedMeshReader (std::vector<double> GetNextNode(); etc) can be called to interrogate the data.

Definition at line 52 of file TrianglesMeshReader.hpp.

Constructor & Destructor Documentation

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

TrianglesMeshReader< ELEMENT_DIM, SPACE_DIM >::TrianglesMeshReader	(	std::string	pathBaseName,
		unsigned	orderOfElements = 1,
		unsigned	orderOfBoundaryElements = 1,
		bool	readContainingElementsForBoundaryElements = false
	)

The containing element for each boundary element (obtaining by doing tetgen with the -nn flag). In a std::vector rather than the struct to save space if not read. Constructor.

Parameters

pathBaseName	the base name of the files from which to read the mesh data (either absolute, or relative to the current directory)
orderOfElements	the order of each element: 1 for linear, 2 for quadratic (defaults to 1)
orderOfBoundaryElements	the order of each boundary element: 1 for linear, 2 for quadratic (defaults to 1. May or may not be different to orderOfElements (Note tetgen with the -o2 flag creates quadratic elements but doesn't create quadratic faces, hence the need for this third parameter)
readContainingElementsForBoundaryElements	Whether to read in the containing element information for each boundary element (in the .face file if tetgen was run with '-nn').
