pyTurbulence is a Python package for generating synthetic compressible turbulent fields for Direct Numerical Simulation (DNS) based on the method of Ristorcelli and Blaisdell. This package provides tools to generate velocity, pressure, and thermodynamic fields, as well as to compute and plot the energy spectrum of the generated turbulence.

## Usage
To use the code from the `example.py` script, follow these steps:
1.**Navigate to the Project Directory**: Open a terminal and navigate to the root directory of the project.
2.**Run the Example Script**: Execute the `example.py` script to generate synthetic turbulence data and save the results.
```sh
python pyTurbulence/example.py
```
3.**View the Results**: The results will be saved in the `results` directory. This includes the generated data files (`u.dat`, `v.dat`, `w.dat`, `p.dat`, `T.dat`), a log file (`log.txt`), and a plot of the energy spectrum (`spectrum.png`).
