Is FluidSim fast enough for professional research?

Yes, it uses Pythran and Transonic compilation to achieve performance comparable to Fortran or C++, and it supports MPI for parallel execution on high-performance computing (HPC) clusters.

How do I analyze the simulation results?

FluidSim includes built-in methods for plotting physical fields (like vorticity), energy spectra, and spatial means directly in Python, and can export data to HDF5 for tools like ParaView.

What equations can FluidSim solve?

FluidSim supports a wide range of equations including 2D and 3D Navier-Stokes, shallow water equations, stratified flows, and specialized solvers for geophysical fluid dynamics.

Do I need specialized hardware to use this skill?

While it runs on standard CPUs, performance is significantly enhanced by FFT libraries and multi-core processors for MPI-enabled parallel solvers.
