Post-processing scripts

This folder contains Python, Shell and Paraview scripts I used for the automatic batch post-processing of OpenFOAM simulations results as part of my PhD journey.

Description

There are three types of code written and used:

1. Employing Paraview's Python API for visualization and data extractions of simulation files. (~10⁷ number points per simulation)
2. Using Python's Matplotlib library to create nice figures with the data extracted
3. Shell scripts

Paraview + Python + Shell

All scripts in the main folder are used for Paraview post-processing. They employ OpenFOAMReader from the Paraview API to read the simulation files created by OpenFOAM-v1812 (can be used pretty much with any version of OpenFOAM). If you are using other input formats this reader needs to be modified accordingly.

All the code is in *.py files that are launched using *.sh scripts with the same file name.

Scripts specify required image sizes and DPI as to conform to the aimed publication page width and length.

Example: for VTK format one can use LegacyVTKReader. Sidenote: as you might guess from the name it will be depricated soon.

Shell scripts

Are serving several purposes:

1. Launch Python code for post-processing using Paraview's API
2. Launch OpenFOAM related processes in the cluster/cloud
3. Synchronization with cluster/cloud using rsync

Python Matplotlib

matplotlib folder contains scripts used for creation of nice figures with the specified image size.

P.S. This scripts took some time for development but saved a lot of time and nerves in turn!) Hope someone will find them useful.
