Pathline#

class ansys.fluent.visualization.Pathline(field, surfaces, solver=None, **kwargs)#

Bases: GraphicsObject

Pathline visualization object.

The Pathline class generates pathlines, which represent the trajectories of massless particles as they travel through the flow field based on the underlying velocity data. Pathlines are commonly used to visualize flow patterns, mixing, recirculation, and streamline-like behavior in transient or steady-state solutions.

Parameters:

  • field (str | VariableDescriptor) – The field used to determine particle motion, typically a velocity-based variable (e.g., "velocity-magnitude", "x-velocity", etc.).

  • surfaces (list[str]) – List of seed surfaces where pathlines originate. These may include boundary zones, inlets, interior surfaces, or user-defined surfaces.

  • solver (FluentSession, optional) – Active Fluent session. If None, the parent class or container determines the session.

  • **kwargs (dict) – Additional keyword arguments forwarded to Graphics(session).Pathlines.create() or handled by the base class.

Examples

>>> from ansys.fluent.visualization import Pathline
>>> # `solver_session` is a live Fluent session with a case
>>> # and data which contains the following surfaces
>>> pathlines = Pathline(
>>>     solver=solver_session,
>>>     field="velocity-magnitude",
>>>     surfaces = ["inlet", "inlet1", "inlet2"],
>>> )
