Member Function Documentation

readMesh()

void rw::reader::MshReader::readMesh	(	size_t	dim,
		std::vector< util::Point3 > *	nodes,
		size_t &	element_type,
		size_t &	num_elem,
		std::vector< size_t > *	enc,
		std::vector< std::vector< size_t >> *	nec,
		std::vector< double > *	volumes,
		bool	is_fd = false
	)

Reads mesh data into node file and element file.

Parameters

dim	Dimension
nodes	Vector of nodes data
element_type	Type of element
num_elem	Number of elements
enc	Vector holding element-node connectivity
nec	Vector holding node-element connectivity
volumes	Vector holding volume of the nodes
is_fd	Flag indicating if this mesh is for finite_difference simulation

readNodes()

void rw::reader::MshReader::readNodes

(

std::vector< util::Point3 > *

nodes

)

Reads nodal position.

Parameters

nodes

Vector of nodal coordinates

readPointData() [1/2]

bool rw::reader::MshReader::readPointData	(	const std::string &	name,
		std::vector< double > *	data
	)

reads point data from .vtu file

Parameters

name	Name of data
data	Pointer to the vector of data

Returns

status True if data is found otherwise false

readPointData() [2/2]

bool rw::reader::MshReader::readPointData	(	const std::string &	name,
		std::vector< util::Point3 > *	data
	)

reads point data from .vtu file

Parameters

name	Name of data
data	Pointer to the vector of data

Returns

status True if data is found otherwise false
