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#
pyansys in user mode, ensure that you have the latest
version of pip with:
python -m pip install -U pip
python -m pip install pyansys
If you are interested in installing an extra target such as
python -m pip install pyansys[fluent-all]
If you are interested in installing a specific version such as
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
Each wheelhouse archive contains all the Python wheels necessary to install
pyansys metapackage from scratch on Windows, Linux, and MacOS from Python
3.8 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 pyansys-v2023.1.dev0-wheelhouse-Linux-3.9-core.zip 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.
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:
XXXXis the Ansys product release year (for example, 2022)
Yis the Ansys product release within the same year (for example, 1, which relates to R1)
ZZis the patched versions to the
pyansysmetapackage, 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:
2024.2.1 2024.2.2 2024.2.3 ...
You can request for a specific version install when pip installing your package:
python -m pip install pyansys==2024.2.0
