Detailed Description

This class represents a group of vtk (Paraview) files that refer to one multiPatch, for one timestep.

This class is used by gsParaviewCollection to manage said files, but can be used by the user explicitly as well.

Constructor & Destructor Documentation

gsParaviewDataSet	(	std::string	basename,
		gsMultiPatch< real_t > *const	geometry,
		gsExprEvaluator< real_t > *	eval = `nullptr`,
		gsOptionList	options = `defaultOptions()`
	)

Basic constructor.

Parameters

basename	The basename that will be used to create all the individual filenames
geometry	A gsMultiPatch of the geometry that will be exported and where the fields are defined
eval	Optional. A gsExprEvaluator, necessary when working with gsExpressions for evaluation purposes
options	A set of options, if unspecified, defaultOptions() is called.

Member Function Documentation

void addField	(	const expr::_expr< E > &	expr,
		std::string	label
	)

inline

Evaluates an expression, and writes that data to the vtk files.

Template Parameters

E

Parameters

expr	The gsExpression to be evaluated
label	The name that will be displayed in Paraview for this field.

void addField	(	const gsField< T >	field,
		std::string	label
	)

inline

Evaluates a gsField ( the function part ), and writes that data to the vtk files.

Template Parameters

T

Parameters

field	The gsField to be evaluated
label	The name that will be displayed in Paraview for this field.

void addFields	(	std::vector< std::string >	labels,
		const expr::_expr< E > &	expr,
		Rest...	rest
	)

inline

Recursive form of addField()

Template Parameters

E
...Rest

Parameters

labels	Vector of strings, containing the names of the fields as they will be shown in ParaView.
expr	The expressions to be evaluated ( arbitrary number of them )
...rest

void addFields	(	std::vector< std::string >	labels,
		const gsField< T >	field,
		Rest...	rest
	)

inline

Recursive form of addField()

Template Parameters

T
...Rest

Parameters

labels	Vector of strings, containing the names of the fields as they will be shown in ParaView.
field	The gsFields to be evaluated ( arbitrary number of them )
...rest

const std::vector< std::string > filenames ( )

Returns the names of the files created by this gsParaviewDataSet.

Returns: A vector of strings

static std::string toDataArray	(	const gsMatrix< T > &	points,
		const std::string	label,
		unsigned	precision,
		const bool &	export_base64
	)

inlinestaticprivate

Formats the coordinates of points as a <DataArray> xml tag for ParaView export.

Template Parameters

T	Arithmetic type

Parameters

points	A gsMatrix<T> with the coordinates of the points, stored column-wise. Its size is (numDims, numPoints)
label	A string with the label of the data
precision	Number of decimal points in xml output
export_base64	(defaults true) export as base63 encoded string - ignore precision

Returns: The raw xml string

static std::vector<std::string> toVTK	(	const gsFunctionSet< T > &	funSet,
		unsigned	nPts = `1000`,
		unsigned	precision = `5`,
		std::string	label = `""`,
		const bool &	export_base64 = `false`
	)

inlinestaticprivate

Evaluates gsFunctionSet over all pieces( patches ) and returns all <DataArray> xml tags as a vector of strings.

Template Parameters

T

Parameters

funSet	gsFunctionSet to be evaluated
nPts	Number of evaluation points, per patch.
precision	Number of decimal points in xml output
label
export_base64	export as base64 encoded string

Returns: Vector of strings of all <DataArrays>

std::vector<std::string> toVTK	(	const expr::_expr< E > &	expr,
		unsigned	nPts = `1000`,
		unsigned	precision = `5`,
		std::string	label = `"SolutionField"`,
		const bool &	export_base64 = `false`
	)

inlineprivate

Evaluates one expression over all patches and returns all <DataArray> xml tags as a vector of strings, as no points are exported, no need to enforce 1:3D fields.

Template Parameters

T

Parameters

expr	Expression to be evaluated
label	The label with which the expression will appear in Paraview
export_base64	export as base64 encoded string

Returns: Vector of strings of all <DataArrays>
