Detailed Description

Flags controlling the details of output in VTK format.

Definition at line 1085 of file data_out_base.h.

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.

Constructor.

double DataOutBase::VtkFlags::time

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 1097 of file data_out_base.h.

unsigned int DataOutBase::VtkFlags::cycle

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 1109 of file data_out_base.h.

bool DataOutBase::VtkFlags::print_date_and_time

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 1117 of file data_out_base.h.

ZlibCompressionLevel DataOutBase::VtkFlags::compression_level

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

Definition at line 1149 of file data_out_base.h.

bool DataOutBase::VtkFlags::write_higher_order_cells

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 sometime in 2017 or 2018. You will need at least Paraview version 5.5 (released in the spring of 2018) or a similarly recent version of Visit for this feature to work (for example, Visit 2.13.2, released in May 2018, 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.
