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:

http://www.paraview.org

The fields to be saved/loaded are:

1. \( \mathbf{r} \) . \( x \)
2. \( \mathbf{r} \) . \( y \)
3. \( \mathbf{r} \) . \( z \) (For 3D cases only)
4. \( \mathbf{n} \) . \( x \)
5. \( \mathbf{n} \) . \( y \)
6. \( \mathbf{n} \) . \( z \) (For 3D cases only)
7. \( \mathbf{u} \) . \( x \)
8. \( \mathbf{u} \) . \( y \)
9. \( \mathbf{u} \) . \( z \) (For 3D cases only)
10. \( \frac{d \mathbf{u}}{dt} \) . \( x \)
11. \( \frac{d \mathbf{u}}{dt} \) . \( y \)
12. \( \frac{d \mathbf{u}}{dt} \) . \( z \) (For 3D cases only)
13. \( \rho \)
14. \( \frac{d \rho}{dt} \)
15. \( m \)
16. moving flag (see Aqua::InputOutput::Fluid::imove)

Constructor & Destructor Documentation

VTK()

Aqua::InputOutput::VTK::VTK	(	ProblemSetup &	sim_data,
		unsigned int	iset,
		unsigned int	offset,
		unsigned int	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)

~VTK()

Aqua::InputOutput::VTK::~VTK

(

)

Destructor.

Member Function Documentation

load()

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

virtual

Load the data.

Implements Aqua::InputOutput::InputOutput.

save()

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

virtual

Save the data.

Parameters

t	Simulation time

Implements Aqua::InputOutput::InputOutput.

waitForSavers()

void Aqua::InputOutput::VTK::waitForSavers ( )

virtual

Wait for the parallel saving threads.

VTK saver is launching parallel threads to save the data in an asynchronous way, significantly improving the performance. Therefore, AQUAgpusph shall wait them to finish before proceeding to destroy the data

Reimplemented from Aqua::InputOutput::Particles.
