If you are using Python 3.10, download and install the wheel file for the vtk package from here for Windows or from here for Linux.

Install the latest release from PyPI with:

pip install ansys-fluent-visualization

There are optional dependencies depending on the desired usage mode. To run the plotter in interactive mode, install with:

pip install ansys-fluent-visualization[interactive]

For interactive mode with graphics displayed in a single Qt window using multiple tabs, install with:

pip install ansys-fluent-visualization[single-window]

Alternatively, install the latest release from GitHub with:

pip install pip -U
pip install -e .

Dependencies

You must have a licensed copy of Ansys Fluent installed locally. PyFluent-Visualization supports Ansys Fluent 2022 R2 and later.

Getting started

Basic usage

The following code assumes that a PyFluent session has already been created and a Fluent case with input parameters has been set up. For a complete example, see Analyzing your results in the PyFluent-Visualization documentation.

from ansys.fluent.visualization import Contour, GraphicsWindow
from ansys.fluent.core.solver import VelocityInlets, PressureOutlets, using
from ansys.units import VariableCatalog

graphics_window = GraphicsWindow()

# Use an existing PyFluent solver session for the duration of this block
with using(solver_session):
   # Define a contour plot of static pressure across all velocity inlets and pressure outlets
    pressure_contour = Contour(field=VariableCatalog.STATIC_PRESSURE, surfaces=VelocityInlets() + PressureOutlets())
    graphics_window.add_graphics(pressure_contour)
    graphics_window.show()

Usage in a JupyterLab environment

PyFluent-Visualization uses PyVista, which has the ability to display fully featured plots within a JupyterLab environment using ipyvtklink. Find out about using ipyvtklink with PyVista here <https://docs.pyvista.org/user-guide/jupyter/ipyvtk_plotting.html>
