Solving Poisson equation using a spectral method, also introducing VTK which will probably be used for other projects
Description on https://compphys.go.ro/solving-poisson-equation/
The project compiles on Windows with Visual Studio 2026 (the code can be compiled with older versions starting with VS 2015, but it's currently maintained with VS 2026 and C++ 17 or higher).
The program requires mfc and the other typical VC++ runtime libraries. Additional libraries needed are FFTW http://www.fftw.org/ and VTK https://vtk.org/.
