17.2 Getting started with PyFluent

• Intro to PyFluent
• PyFluent documentation

Install sequentially the following packages as described here:

pip install ansys-fluent-core
pip install ansys-fluent-parametric
pip install ansys-fluent-visualization

Note: ansys-fluent-parametric requires an outdated version of NumPy (<2.0), so you probably need to consider working in a virtual environment.
