get_streamlines(n_points=100, initial_step_length=1, source_radius=1.1, source_center=(0, 0, 0), streamline_radius=0.005)

Generates streamlines from the domain mesh.

Parameters:

• n_points (int, optional) – Number of streamlines. Defaults to 100.

• initial_step_length (float, optional) – Initial step length. Defaults to 1.

• source_radius (float, optional) – Radius of seeding sphere. Defaults to 1.1.

• source_center (tuple, optional) – Center of seeding sphere. Defaults to (0, 0, 0).

• streamline_radius (float, optional) – Radius of streamlines. Defaults to 0.005.

Returns:

Streamlines as tube-shaped meshes.

Return type:

pv.PolyData
