PostProc: A post-processing package for my PhD CFD simulations

This library has the goal of gathering all the python scripts I write for post-processing data from my Computational Fluid Dynamics simulations (CFD) I run for my PhD. By making it public I hope someone else can find this useful as well.

This repository contains the postproc package provided with the following tools

• cylinder_forces.py: a set of functions which allow to extract useful information from the forces on a body provided with a time series of the lift force.

• averages.py: module containing functions to compute flow field operations such as derivatives, averages, decompositions and vorticity.

• io.py: functions related to import binary data from Fortran simulations. Imports 2D or 3D flow fields with a specified number of components. It imports also text files written in columns with the unpack* functions.

• plotter.py: module equipped with subroutines to plot a 2D contour and CL-t graphs.

Installation

To install this package in your workstation just make sure tot have git and pip3 installed and then run

$ git clone https://github.com/b-fg/postproc.git $ cd postproc $ sudo pip3 install . -r requirements.txt

This will install the postproc package at you python3 libraries folder (probably /usr/lib/python3/dist-packages) with the declared required packages in requirements.txt. This way the package will be available from any path.
If you wish to make modifications and make them ready straight-away use also -e on the pip3 install command. This provides the source path of the package to the installed library so any modification is immediately available with no need to re-install.

Usage

Add in your python script:

import postproc.averages as averages
import postproc.cylinder_forces as cf
import postproc.io as io
import postproc.plotter as plotter

To add all of the packages modules. See /test folder for sample scripts (sample data is included).
