How do I visualize the results?

You can use the built-in plot() methods for physical fields and spectra, or export HDF5 files for advanced 3D visualization in ParaView.

What equations can FluidSim solve?

FluidSim includes solvers for 2D/3D Navier-Stokes equations, shallow water equations, and stratified flows for oceanic or atmospheric modeling.

Can I define custom initial conditions?

Absolutely. You can set the initial field type to 'in_script' and define velocity or density fields directly using NumPy-like syntax within the simulation setup.

Is it faster than standard Python?

Yes, it uses Pythran and Transonic compilation to achieve performance comparable to Fortran or C++ while keeping a Python interface.

Does FluidSim support parallel computing?

Yes, it supports MPI parallelization, allowing you to scale simulations across multiple processors on high-performance clusters.

Executes high-performance computational fluid dynamics simulations and analysis using pseudospectral methods in Python.

소개

FluidSim is a specialized Python framework designed for high-performance computational fluid dynamics (CFD) simulations, enabling researchers and engineers to solve complex equations like Navier-Stokes, shallow water, and stratified flows. By leveraging pseudospectral methods with FFT and MPI parallelization, it offers the performance of Fortran or C++ while maintaining Python's developer-friendly syntax. This skill is ideal for modeling turbulence, vortex dynamics, and geophysical flows, providing a comprehensive workflow from initial parameter configuration and execution to interactive visualization and output analysis.
