FAQPage Schema
How do I run Navier-Stokes simulations in Python without writing low-level code?

CFD simulations of shallow-water and stratified flows require pseudospectral methods using Fast Fourier Transforms (FFT) for high spatial accuracy. This approach handles complex geophysical fluid dynamics efficiently by transforming equations into spectral space for derivative calculations.

Can I use MPI to parallelize high-performance CFD runs for parametric studies?

To configure 2D and 3D Navier-Stokes solvers, you define simulation parameters within a Python environment to set initial conditions and boundary behaviors. The framework then automates the pseudospectral solver selection and data output configuration for your specified turbulence or vortex dynamics scenario.

What is the best way to perform post-processing analysis on geophysical flow outputs?

The best way to perform post-processing on geophysical flow outputs is to use built-in interactive analysis and visualization tools within the simulation framework. This allows researchers to directly compute energy spectra and analyze turbulent flow data immediately after the run completes.

Does pseudospectral CFD simulation work for both shallow-water and stratified flow scenarios?

Yes, pseudospectral CFD simulation works for shallow-water and stratified flow scenarios. The framework explicitly supports these geophysical fluid models alongside 2D and 3D Navier-Stokes equations, allowing researchers to model complex density-layered dynamics efficiently.
