This is a Python framework for running computational fluid dynamics simulations using pseudospectral methods. You'd use it for 2D/3D Navier-Stokes, shallow water equations, stratified flows, or turbulence analysis. The workflow is straightforward: import a solver, configure parameters via dot notation, instantiate, and run. It compiles with Pythran for performance, supports MPI parallelization, and automatically outputs HDF5 fields, spectra, and spatial means you can analyze in Python or ParaView. The hierarchical parameter system catches typos with AttributeError, which saves debugging time. Installation requires FFT libraries, and most realistic simulations will need the MPI flag for anything above toy resolutions.
