The objective of this code is to provide a way to systematically identify, count and raise statistics of vortical structures in turbulent flow.

The input is a 2D velocity field, which can either be a true 2D flow or a cross cut from a 3D velocity field. As of the present moment, this flows include synthetic 2D flows used to validate the identification part of the code and, ongoing, input from openFOAM files.

Vortex_Id needs the following libraries and programs installed in your system

Cmake
GSL : Gnu Scientific Library
inih : Ini file reader Library
numpy & matplotlib : python array and ploting libraries
A C99 compliant compiler (gcc 4.8.4 and icc 16.0.0 were tested)

Instalation instructions:

Create folders named obj (for .o files), bin (for executables) and data (for results)
run make for main essay executable or main for the executable of your choice
If everything went well, everything should compile, even with some warnings it is not problematic.
All executables are stored on the bin folder
