Member Function Documentation

Process()

TPZGeoMesh * TPZReadTetGen::Process	(	std::string	NodeFileName,
		std::string	FaceFileName,
		std::string	TetraFileName
	)

Convert tetgen files in a TPZGeoMesh object.

If something does not work in the process, a null pointer is returned.

ProcessFaces()

bool TPZReadTetGen::ProcessFaces ( std::string  FaceFileName, TPZGeoMesh &  gmesh, int64_t &  numberfaces  )

private

Process faces.

Returns true if the process worked succesfuly and false otherwise.

Member Data Documentation

fNodeIndices

std::map<int64_t, int64_t> TPZReadTetGen::fNodeIndices

private

Nodes in tetgen are counted from 1 to n as a fortran based code.

In PZ, nodes have one Id and one index. index is defined by TPZGeoMesh when a new node is allocated in NodeVec(). This object maps from the Id to the index. fNodeIndices[ Id ] = index.
