|
# For post-processed VTK files that form a series, foamVTKSeries writes a

# '.vtk.series' file with filenames and corresponding times, which can be
|
|
# opened in ParaView.
|
|
#
|
|
# ParaView then interprets the files as a sequence which can be played with

|
# video controls.

For post-processed VTK files that form a series, foamVTKSeries writes a
|
|
'.vtk.series' file with filenames and corresponding times, which can be opened
|
|
in ParaView. ParaView then interprets the files as a sequence which can be
|
|
played with video controls.
|
|
|
|
VTK files are typically written into time directories within a named "function"
|
|
sub-directory of the case 'postProcessing' directory, e.g.
|
|
'postProcessing/patchSurface/0.1/patch.vtk', where 'patchSurface' is the
|
|
function sub-directory and '0.1' is the time directory.
|
|
|
|
Series files use the same prefix as the VTK files and are written into the
|
|
function sub-directory, i.e. 'postProcessing/patchSurface/patch.vtk.series' in
|
|
our example.
