Detailed Description

VTK export.

export class to VTK ( http://www.kitware.com/vtk.html ) file format (not the XML format, but the old format)

A vtk_export can store multiple scalar/vector fields.

Member Function Documentation

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 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 209 of file getfem_export.h.

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 241 of file getfem_export.h.

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 235 of file getfem_export.h.

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
