tecio.plt

Read and write Tecplot PLT (.plt) binary files.

Tecplot PLT is the classic Tecplot binary format, supported by both v112 and v191 file versions.

Key behaviours:

• Zone metadata is parsed eagerly at open time; variable data is read lazily from disk on first access.

• The writer uses the classic TecIO API, which maintains a single implicit global file context — only one PLT file may be open for writing at a time.

• Zone data must be written in strict order: zone header, then variable data, then connectivity before starting the next zone.

• FEPOLYGON and FEPOLYHEDRON zone types are not supported by the writer.

Example

>>> with tecio.open("out.plt", "w") as w:
...     w.write_ijk_zone(
...         data=[x, y, p],
...         variables=["x", "y", "pressure"],
...     )
