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.

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

inline

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

Template Parameters

T

Parameters

funSet	gsFunctionSet to be evaluated
nPts	Number of evaluation points, per patch.
precision	Number of decimal points in xml output

Template Parameters

T

Parameters

expr	Expression to be evaluated
label	The label with which the expression will appear in Paraview
