Detailed Description

VTK/VTU export.

export class to VTK/VTU file format ( http://www.kitware.com/vtk.html, legacy and serial vtkUnstructuredGrid)

A vtk_export can store multiple scalar/vector fields.

Member Function Documentation

write_point_data()

template<class VECT >

void getfem::vtk_export::write_point_data	(	const getfem::mesh_fem &	mf,
		const VECT &	U0,
		const std::string &	name
	)

append a new scalar or vector field defined on mf to the .vtk/.vtu file.

If you are exporting a slice, or if mf != get_exported_mesh_fem(), U will be interpolated on the slice, or on get_exported_mesh_fem().

Note that vectors should be written AFTER scalars, and tensors after vectors

NO SPACE ALLOWED in 'name'

Definition at line 201 of file getfem_export.h.

write_sliced_point_data()

template<class VECT >

void getfem::vtk_export::write_sliced_point_data	(	const VECT &	Uslice,
		const std::string &	name,
		size_type	qdim = 1
	)

append a new scalar or vector field to .vtk file.

The Uslice vector is the field interpolated on the exported mesh_slice This function should not be used if you are not exporting a slice! NO SPACE ALLOWED in 'name'

Definition at line 233 of file getfem_export.h.

write_cell_data()

template<class VECT >

void getfem::vtk_export::write_cell_data	(	const VECT &	U,
		const std::string &	name,
		size_type	qdim = 1
	)

export data which is constant over each element.

You should not use this function if you are exporting a slice. U should have convex_index().card() elements.

Definition at line 227 of file getfem_export.h.

write_mesh_quality()

void getfem::vtk_export::write_mesh_quality

(

const mesh &

m

)

export a data_set correspounding to measures of quality for each convex of the supplied mesh (which should have the same number of convex than the one used in the vtk_export)

If a slice is being exported, the convex quality is written as point_data (TO IMPROVE ONEDAY), if a mesh/mesh_fem is being exported, it is written as cell_data
