animated_plot.sh

Go to the documentation of this file.

#!/bin/bash
# This script generates a animated plot movie using series of png plots. 
# Default plot is crack area against load factor. Plot setttings can be changed 
# by modifying the gnuplot script get_animated_plot.gnu
# 
# Input:
#           displacement_loadFactor_crackArea_energy.csv
# 
# Output:
#           animated_plot.mp4
# 
# Usage:
#       1. Change working directory to the place where csv file is located. 
#           This csv file is generated after running plotting_data.sh
#           
#       2. Make sure animated_plot.sh and get_animated_plot.gnu are accessible 
#           from the working directory. This can be done by either copying 
#           those two files to the working directory or adding them to the same 
#           PATH (in .bashrc or .bash_profile)
# 
#       3. Make sure package ffmpeg is installed and loaded by a package 
#           manager, for example, spack.
# 
#       4. If needed, modify parameter 'fps' in animated_plot.sh to the desired
#           number of frames per second for the output movie
# 
#       5. Run animated_plot.sh
#
#       6. Obtain animated movie, animated_plot.mp4, in the same directory. 
#           Movie will be opened automatically if macOS is used.
