Data Flow

All readers return the same three-dict tuple, and all writers accept it:

read_file(path)  →  (grid_dict, flow_dict, attrs_dict)  →  write_file(path, ...)

Dict	Contents	Example keys
grid_dict	Coordinate arrays	"x", "y", "z"
flow_dict	Solution variables	"rho", "u", "v", "w", "p"
attrs_dict	Metadata	"mach", "re", "nx", "ny", "nz"

Format Dispatch

read_file and write_file resolve the file format from the extension:

Extension	Format	Reader	Writer
.h5, .hdf5	HDF5	read_hdf5	write_hdf5
.x, .xyz	Plot3D grid	read_plot3d	write_plot3d
.q	Plot3D solution	read_plot3d_flow	—
.dat	Tecplot ASCII	read_tecplot_ascii	write_tecplot_ascii
.plt	Tecplot binary	read_tecplot_plt	write_tecplot_plt
.s8, .s4	Raw binary (split)	read_binary_direct	write_binary_direct
