Getting started#

PyAnsys libraries fall into two categories:

Most PyAnsys packages require a local installation of Ansys. The version of Ansys installed dictates the interface and features available to you. However, PyAnsys libraries use grpc to communicate to the products, you can have the product installed remotely and connect to that remote instance. This still requires that you need a copy of Ansys installed on the host machine.

For more information on getting a licensed copy of Ansys, visit Ansys. If you are a student, consider installing a student version by visiting Ansys for Students.


There are several ways of installing PyAnsys depending on your use case, but the easiest is simply to run:

pip install pyansys

This installs all the PyAnsys libraries for the latest released version of Ansys, for example, v2023R1.

You can always install libraries individually by visiting the install page for each library. For example, for PyAEDT:

pip install pyaedt

User mode installation#

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

python -m pip install -U pip

Then, install pyansys with:

python -m pip install pyansys

If you are interested in installing an extra target such as fluent-all:

python -m pip install pyansys[fluent-all]

If you are interested in installing a specific version such as 2023.1.0:

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 pyansys metapackage from scratch on Windows, Linux, and MacOS from Python 3.9 to 3.11. You can install this on an isolated system with a fresh Python installation or on a virtual environment.

For example, on Linux with Python 3.9, unzip the wheelhouse archive and install it with the following:

unzip wheelhouse
pip install pyansys -f wheelhouse --no-index --upgrade --ignore-installed

If you’re on Windows with Python 3.9, unzip to a wheelhouse directory and install using the same command as above.

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. In that sense, the following kind of versioning system is followed:



  • 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 the patched versions to the pyansys metapackage, if any.

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


And any subsequent patched version of that package would be:


You can request for a specific version install when pip installing your package:

python -m pip install pyansys==2024.2.0
