ansys-speos-core 0.7.4

A Python wrapper for Ansys Speos

Project overview

PySpeos is a Python library that gathers functionalities and tools based on remote API provided by gRPC server of Ansys software Speos .

Installation

Installation can be done using the published package or the repository sources.

Package

This repository is deployed as the Python packages ansys-speos-core. As usual, installation is done by running:

pip install ansys-speos-core

Sources

Prerequisite: user needs to have a GitHub account and a valid Personal Access Token (see GitHub Settings/Developer settings/Personal access tokens/Generate new token).

Clone and install

git clone https://github.com/ansys/pyspeos.git
cd pyspeos
python -m pip install --upgrade pip
pip install -U pip tox
tox -e style
pip install -e .

Functionalities

All sources are located in src/ folder.

from ansys.speos.core.speos import Speos

speos = Speos()

Documentation and issues

Documentation for the latest stable release of PySpeos is hosted at PySpeos Documentation.

In the upper right corner of the documentation’s title bar, there is an option for switching from viewing the documentation for the latest stable release to viewing the documentation for the development version or previously released versions.

On the PySpeos Issues page, you can create issues to report bugs and request new features. On the PySpeos Discussions page or the Discussions page on the Ansys Developer portal, you can post questions, share ideas, and get community feedback.

To reach the project support team, email [e-mail].

The documentation sources are stored in doc folder and generated using Sphinx. To build it manually :

pip install -U pip tox
pip install .[doc]
tox -e doc && your_browser_name .tox/doc_out/index.html

Testing

Tests and assets are in tests and tests/assets folder. Running PySpeos tests requires a running SpeosRPC server. A configuration file allows to choose between a local server and a Docker server (by default).

Test configuration file

The configuration file tests/local_config.json located in tests folder contains several parameters that can be changed according to your needs, for example:

• SpeosServerOnDocker (Boolean): Speos server launched in a Docker container.

• SpeosServerPort (integer): Port used by Speos server for HTTP transfer.

Start server

The first option is to use the Docker image from the PySpeos repository on Github.

Note

This option is only available for users with write access to the repository or who are members of the Ansys organization.

Use a GitHub personal access token with permission for reading packages to authorize Docker to access this repository. For more information, see Managing your personal access tokens in the GitHub documentation. Save the token to a file with this command:

echo XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX > GH_TOKEN.txt

Since the Docker image contains no license server, you will need to enter your license server IP address in the LICENSE_SERVER environment variable. Then, to launch SpeosRPC server with product version 2025.1, you can run:

export GH_USERNAME=<my-github-username>
export LICENSE_SERVER=[e-mail]

cat GH_TOKEN.txt | docker login ghcr.io -u "$GH_USERNAME" --password-stdin
docker pull ghcr.io/ansys/speos-rpc:252
docker run --detach --name speos-rpc -p 127.0.0.1:50098:50098 -e ANSYSLMD_LICENSE_FILE=$LICENSE_SERVER --entrypoint /app/SpeosRPC_Server.x ghcr.io/ansys/speos-rpc:252 --transport_insecure --host 0.0.0.0

Note

To use the latest image in development, you can use ghcr.io/ansys/speos-rpc:dev.

On the other hand, the SpeosRPC server can be started locally.

For Windows:

%AWP_ROOT251%\Optical Products\SPEOS_RPC\SpeosRPC_Server.exe

For Linux:

$AWP_ROOT251\OpticalProducts\SPEOS_RPC\SpeosRPC_Server.x

And test configuration file tests/local_config.json must be updated to use local server:

{
   "SpeosServerOnDocker": false,
   "SpeosContainerName" : "speos-rpc",
   "SpeosServerPort": 50098
}

Launch unit tests

pip install .[tests]
pytest -vx

Use jupyter notebook

pip install .[jupyter]
jupyter notebook

jupyter notebook can be downloaded from the documentations example section.
