What types of flows can I simulate with this skill?

You can simulate a wide range of flows including 2D and 3D Navier-Stokes, shallow water equations, stratified flows, and various geophysical or atmospheric models.

Is Python fast enough for fluid simulations?

Yes, FluidSim uses Pythran and Transonic for ahead-of-time compilation, achieving performance levels comparable to Fortran or C++ while keeping the ease of Python.

Does FluidSim support parallel computing?

Yes, FluidSim supports MPI parallelization, allowing you to run high-resolution simulations across multiple processors or on high-performance computing (HPC) clusters.

How do I analyze the simulation results?

FluidSim includes built-in analysis tools to plot physical fields like vorticity and velocity, calculate spatial means, and visualize energy or enstrophy spectra.

FluidSim is an object-oriented Python framework for high-performance computational fluid dynamics (CFD) that uses pseudospectral methods and FFT for efficient simulation.
