• PyMaterials Manager: Python package for unifying material management across the Ansys portfolio.

Much effort is underway to continue expanding and developing packages in the PyAnsys GitHub account. On the Issues page for each package, you can post issues and request new features. You can also feel free to post a question on the Ansys Developer Forums.

Additionally, the pyansys metapackage contains certain extra targets that can be installed upon request:

• mapdl-all: This target installs the core packages and PyMAPDL Reader.

• fluent-all: This target installs the core packages, and PyFluent - Visualization.

• tools: This target installs the core packages, Ansys FileTransfer Tool, Ansys Tools Common, PyAnsys Tools Variable Interop, PyAnsys Units, and PyMaterials Manager.

• all: This target installs all extra pyansys packages.

Package installation

Two installation modes are provided: user and offline.

User mode installation

Before installing the pyansys metapackage in user mode, ensure that you have the latest version of pip with this command:

python -m pip install -U pip

Then, install the pyansys metapackage with this command:

python -m pip install pyansys

If you are interested in installing an extra target such as fluent-all, you use a command like this:

python -m pip install pyansys[fluent-all]

If you are interested in installing a specific version such as 2023.1.0, you use a command like this:

python -m pip install pyansys==2023.1.0

Offline mode installation

If you lack an internet connection on your installation machine, the recommended way of installing the pyansys metapackage is downloading the wheelhouse archive from the Releases Page for your corresponding machine architecture.

Each wheelhouse archive contains all the Python wheels necessary to install the pyansys metapackage from scratch on Windows, Linux, and MacOS from Python 3.10 to 3.14. You can install this on an isolated system with a fresh Python installation or on a virtual environment.

For example, on Linux with Python 3.10, unzip the wheelhouse archive and install it with the following commands:

unzip pyansys-v2026.1.2-wheelhouse-Linux-3.10-core.zip wheelhouse
pip install pyansys -f wheelhouse --no-index --upgrade --ignore-installed

If you’re on Windows with Python 3.10, unzip to a wheelhouse directory and then install using the same pip command as in the previous example.

Consider installing using a virtual environment.

Versioning system

The pyansys metapackage follows a semantic-like versioning system, though it has been adapted to the Ansys product release mechanism. Thus, this kind of versioning system is followed:

XXXX.Y.ZZ

Where:

• XXXX is the Ansys product release year (for example, 2022).

• Y is the Ansys product release within the same year (for example, 1, which relates to R1).

• ZZ is a patched version to the pyansys metapackage, if any.

Consequently, the first pyansys metapackage compatible with the 2024 R2 release would be:

2024.2.0

Any subsequent patched version of this package would be:

2024.2.1
2024.2.2
2024.2.3
...

You can request a specific version install when using pip to install your package:

python -m pip install pyansys==2024.2.0
