Data Structures (ldc.datastructures)

Configuration and result data structures for solvers.

Parameters	Base solver parameters - input configuration for all solvers.
FVParameters	FV solver parameters (extends Parameters with SIMPLE-specific settings).
SpectralParameters	Spectral solver parameters (nx/ny = polynomial order N, giving N+1 nodes).
Metrics	Solver metrics - output results computed during/after solving.
Fields	Spatial solution fields (u, v, p) on grid (x, y).
TimeSeries	Convergence history (one value per iteration).
FVSolverFields	Internal FV solver arrays - current state, previous iteration, and work buffers.
SpectralSolverFields	Internal spectral solver arrays - current state and work buffers.
