Simulates high-performance computational fluid dynamics using pseudospectral methods and Python-based solvers.
FluidSim is a powerful object-oriented Python framework designed for high-performance computational fluid dynamics (CFD). It specializes in solving periodic-domain equations using pseudospectral methods with FFT, providing performance comparable to C++ or Fortran while maintaining Python's ease of use. It supports a wide range of solvers, including 2D/3D Navier-Stokes, shallow water equations, and stratified flows, making it an essential tool for researchers and engineers studying turbulence, vortex dynamics, and geophysical flows.
