# foamSequenceVTKFiles
#
# 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
