Detailed Description

VTK particles data files loader/saver.

VTK is a visualization format, to learn more about it please visit the following web page:

http://www.vtk.org

This type of files can be easily post-processed with Paraview:

The fields to be saved/loaded are:

\( \mathbf{r} \) . \( x \)
\( \mathbf{r} \) . \( y \)
\( \mathbf{r} \) . \( z \) (For 3D cases only)
\( \mathbf{n} \) . \( x \)
\( \mathbf{n} \) . \( y \)
\( \mathbf{n} \) . \( z \) (For 3D cases only)
\( \mathbf{u} \) . \( x \)
\( \mathbf{u} \) . \( y \)
\( \mathbf{u} \) . \( z \) (For 3D cases only)
\( \frac{d \mathbf{u}}{dt} \) . \( x \)
\( \frac{d \mathbf{u}}{dt} \) . \( y \)
\( \frac{d \mathbf{u}}{dt} \) . \( z \) (For 3D cases only)
\( \rho \)
\( \frac{d \rho}{dt} \)
\( m \)

Constructor & Destructor Documentation

◆ VTK()

Aqua::InputOutput::VTK::VTK	(	ProblemSetup &	sim_data,
		unsigned int	iset,
		size_t	offset,
		size_t	n = 0 )

Constructor.

Parameters

sim_data	Simulation data
iset	Particles set index.
offset	First particle managed by this saver/loader.
n	Number of particles managed by this saver/loader. If 0, the number of particles will be obtained from the input file (thus only valid for loaders)

Here is the call graph for this function:

◆ ~VTK()

Aqua::InputOutput::VTK::~VTK ( )

Destructor.

Member Function Documentation

◆ load()

void Aqua::InputOutput::VTK::load ( )

virtual

Load the data.

Implements Aqua::InputOutput::InputOutput.

◆ print_file()

void Aqua::InputOutput::VTK::print_file ( )

finalvirtual

Print the data to a file.

Note: This method is public to work with the OpenCL callbacks, but it is not meant to be called by the users

Reimplemented from Aqua::InputOutput::Particles.

◆ save()

void Aqua::InputOutput::VTK::save ( float t )
