# Description
|
|
# Creates symbolic links to all VTK files in a post-processing directory
|
|
# Links form a sequence like name.0000.vtk, name.0001.vtk, etc.
|
|
# Paraview recognises link names as a sequence which can be animated.
|
|
# The sequence of links can be used to create a video from the images.
|
|
# - Default directory name for VTK files is postProcessing
