class tud_lbm.io.plotting.velocity.VelocityPlotOperator(config: tud_lbm.config.SimulationConfig, data_dir: str | pathlib.Path | None = None)

Bases: tud_lbm.io.plotting.base.PlotOperator

Render velocity magnitude with a downsampled vector overlay.

name = 'velocity'

is_available(data: dict[str, numpy.ndarray]) → bool

Check if velocity data is available in the dataset.

Parameters:

data – Dictionary containing simulation output data.

Returns:

True if velocity field ‘u’ is present in data, False otherwise.

__call__(ax: matplotlib.axes.Axes, data: dict[str, numpy.ndarray], timestep: int) → None

Render velocity magnitude with a downsampled vector overlay.

Parameters:

• ax – Matplotlib axes object to plot on.

• data – Dictionary containing simulation output data with velocity field.

• timestep – Current simulation timestep for display in title.
