Detailed Description

Flags for grid output in Vtk format. These flags are the same as those declared in DataOutBase::VtkFlags.

Definition at line 859 of file grid_out.h.

Member Enumeration Documentation

◆ ZlibCompressionLevel

A data type providing the different possible zlib compression levels. These map directly to constants defined by zlib.

Enumerator
no_compression 

Do not use any compression.

best_speed 

Use the fastest available compression algorithm.

best_compression 

Use the algorithm which results in the smallest compressed files. This is the default flag.

default_compression 

Use the default compression algorithm. This is a compromise between speed and file size.

Definition at line 1125 of file data_out_base.h.

Constructor & Destructor Documentation

◆ Vtk()

GridOutFlags::Vtk::Vtk ( const bool  output_cells = true,
const bool  output_faces = true,
const bool  output_edges = true,
const bool  output_only_relevant = true 
)
inline

Default constructor.

Definition at line 864 of file grid_out.h.

Member Function Documentation

◆ declare_parameters()

void DataOutBase::OutputFlagsBase< VtkFlags >::declare_parameters ( ParameterHandler prm)
staticinherited

Declare all flags with name and type as offered by this class, for use in input files.

This method does nothing, but child classes may override this method to add fields to prm.

Definition at line 577 of file data_out_base.h.

◆ parse_parameters()

void DataOutBase::OutputFlagsBase< VtkFlags >::parse_parameters ( const ParameterHandler prm)
inherited

Read the parameters declared in declare_parameters() and set the flags for this output format accordingly.

This method does nothing, but child classes may override this method to add fields to prm.

Definition at line 583 of file data_out_base.h.

◆ memory_consumption()

std::size_t DataOutBase::OutputFlagsBase< VtkFlags >::memory_consumption ( ) const
inherited

Return an estimate for the memory consumption, in bytes, of this object. This is not exact (but will usually be close) because calculating the memory usage of trees (e.g., std::map) is difficult.

Definition at line 589 of file data_out_base.h.

Member Data Documentation

◆ output_cells

bool GridOutFlags::Vtk::output_cells

Output cells.

Definition at line 877 of file grid_out.h.

◆ output_faces

bool GridOutFlags::Vtk::output_faces

Output faces.

Definition at line 882 of file grid_out.h.

◆ output_edges

bool GridOutFlags::Vtk::output_edges

Output co-faces/edges.

Definition at line 887 of file grid_out.h.

◆ output_only_relevant

bool GridOutFlags::Vtk::output_only_relevant

Output only faces/co-faces that differ from the default settings (e.g boundary_id).

Definition at line 893 of file grid_out.h.

◆ time

double DataOutBase::VtkFlags::time
inherited

The time of the time step if this file is part of a time dependent simulation.

The value of this variable is written into the output file according to the instructions provided in http://www.visitusers.org/index.php?title=Time_and_Cycle_in_VTK_files unless it is at its default value of

std::numeric_limits<unsigned int>::min() 

.

Definition at line 1099 of file data_out_base.h.

◆ cycle

unsigned int DataOutBase::VtkFlags::cycle
inherited

The number of the time step if this file is part of a time dependent simulation, or the cycle within a nonlinear or other iteration.

The value of this variable is written into the output file according to the instructions provided in http://www.visitusers.org/index.php?title=Time_and_Cycle_in_VTK_files unless it is at its default value of

std::numeric_limits<unsigned int>::min() 

.

Definition at line 1111 of file data_out_base.h.

◆ print_date_and_time

bool DataOutBase::VtkFlags::print_date_and_time
inherited

Flag to determine whether the current date and time shall be printed as a comment in the file's second line.

Default is true.

Definition at line 1119 of file data_out_base.h.

◆ compression_level

ZlibCompressionLevel DataOutBase::VtkFlags::compression_level
inherited

Flag determining the compression level at which zlib, if available, is run. The default is best_compression.

Definition at line 1151 of file data_out_base.h.

◆ write_higher_order_cells

bool DataOutBase::VtkFlags::write_higher_order_cells
inherited

Flag determining whether to write patches as linear cells or as a high-order Lagrange cell.

Default is false.

Note
The ability to write data that corresponds to higher order polynomials rather than simply linear or bilinear is a feature that was only introduced in VTK 8.1.0 in December 2017. You will need at least Paraview version 5.5.0 released in April 2018 or a similarly recent version of VisIt for this feature to work (for example, VisIt 3.1.1, released in February 2020, does not yet support this feature). Older versions of these programs are likely going to result in errors when trying to read files generated with this flag set to true. Experience with these programs shows that these error messages are likely going to be rather less descriptive and more obscure.
