   Bases: :py:obj:`tud_lbm.io.output_data.base.OutputWriter`


   Output writer that saves data in VTK format.


   .. py:method:: save_data_step(iteration: int, data: dict[str, numpy.ndarray]) -> None

      Write output data in VTK format.

      Handles both 2D and 3D scalar/vector fields from the simulation state.

      For 5D state arrays (nx, ny, nz, q, 1):
      - Scalar fields: Extracted as (nx, ny, nz) via field[..., 0, 0]
      - Vector fields: Extracted as (nx, ny, nz, d) tuples, padding to 3D

      :param iteration: The iteration number.
      :param data: Dictionary mapping field names to numpy arrays.

      :raises RuntimeError: If pyevtk is not installed.
