PPUN2D – Post-Processing Tool for Unstructured 2D CFD Solutions

PPUN2D (Post-Processing Unstructured 2D Data) is a C++ software developed for the aerodynamic force computation and drag decomposition from CFD solutions on unstructured 2D grids. The code originates from the structure and methodology of UBF2D, a structured-grid code developed by Dr. Mauro Minervino (CIRA) and by the University of Naples "Federico II" (https://github.com/UNINA-TAARG/UBF2D). It supports both near-field and far-field approaches and includes Green-Gauss gradient reconstruction and domain decomposition techniques. The software is intended for academic and research purposes.
