Detailed Description

template<size_t dimension>
class Manicore::Exporter< dimension >

Evaluate vector of discrete unknowns and store them in files.

This class compute and store all the necessary data when constructed.

Template Parameters

dimension

Dimension of the manifold

Constructor & Destructor Documentation

Exporter()

template<size_t dimension>

Exporter::Exporter	(	Mesh< dimension > const *	mesh,
		int	r,
		int	acc
	)

Constructor.

The constructor store the mapping between the cell and the embedding at each point. This may requires a significant amount of space. The location chosen to print the value are computed using the quadrature formulas. The degree acc, is not directly the number of location per cell, but the degree of the formula used.

The distribution may not be uniform, and may depends of the triangulation of the reference element in each cell.

Parameters

mesh	Reference to the mesh used
r	Polynomial degree
acc	Degree of the quadrature

Member Function Documentation

save()

template<size_t dimension>

int Exporter::save	(	size_t	k,
		std::function< Eigen::VectorXd(size_t iT)>	Fu_h,
		const char *	filename,
		bool	star = false
	)		const

Write a csv file with the point-wise value of the discrete function.

By default, this use the identification between 0-forms and function, and between 1-forms and vector. In 2D, there is an ambiguity between \(1\) and \(n-1\) forms. By default, this function will print an \(1\)-form, set star=true to reverse the behavior.

Remarks

The DDR_Spaces::potential() operator returns the Hodge star of the potential

Parameters

k	Form degree
Fu_h	Return the discrete vector in \(\mathcal{P}_r\Lambda^k(\mathbb{R}^d)\) in a given cell iT
filename	Name and location to write the data
star	Apply the Hodge star before exporting an 1-form

saveSq()

template<size_t dimension>

int Exporter::saveSq	(	size_t	k,
		std::function< Eigen::VectorXd(size_t iT)>	Fu_h,
		const char *	filename
	)		const

Write a csv file with the point-wise value of the contraction of the function with itself.

Compute \( u^i u_i \)

Parameters

k	Form degree
Fu_h	Return the discrete vector in \(\mathcal{P}_r\Lambda^k(\mathbb{R}^d)\) in a given cell iT
filename	Name and location to write the data
