SDPM

SDPM is an open-source C++/Python, unsteady compressible source and doublet panel method, developed at the University of Liège by Adrien Crovato and Grigorios Dimitriadis, during the academic years 2022-2024. SDPM is currently capable of rapidly solving steady or unsteady compressible subsonic flows on isolated or multiple wings, as well as calculating the aerodynamic forces gradients. Furthermore, the code is interfaced with OpenMDAO so that aeroelastic computations and optimization can be easily carried out.

Main features

• Cross platform (Windows and Unix) C++/Python code
• Physical model
  • unstructured quadrangle meshes for 3D geometries using Gmsh
  • steady and unsteady flows
  • subsonic compressile flows with transonic correction
• Numerical methods
  • linear algrebra using Eigen
  • reverse automatic differentiation using CoDiPack
