A Python client for Ansys Composite PrepPost (ACP).

Overview

Installation

Install PyACP with:

.. code-block::

pip install ansys-acp-core

For installing PyACP in development mode, see the Development Setup_ instructions below.

Documentation

The PyACP documentation can be viewed online at https://acp.docs.pyansys.com.

.. _launching_server:

Getting Started

Launching ACP ^^^^^^^^^^^^^

The ACP server can be started with launch_acp:

.. code-block:: python

import ansys.acp.core as pyacp

acp = pyacp.launch_acp()

Basic Usage ^^^^^^^^^^^

Once the server is running, we can start working with PyACP. For example, to load an ACP Model from an existing file:

.. code-block:: pycon

>>> remote_filename = acp.upload_file(local_path="<MODEL_PATH>")
>>> model = acp.import_model(path=remote_filename)
>>> model.name
'ACP Model'

Development Setup

Installation ^^^^^^^^^^^^

Installing PyACP in developer mode allows you to modify the source and enhance it. Before contributing to the project, please refer to the PyAnsys Developer's guide_.

You will need to follow these steps:

  1. Start by cloning this repository, and entering the newly created directory:

    .. code-block:: bash

    git clone https://github.com/ansys/pyacp
cd pyacp

  2. Make sure you have the latest version of poetry:

    .. code-block:: bash

    python -m pip install pipx
pipx ensurepath
pipx install poetry

    .. note::

    At this point, you may need to restart your shell or editor to ensure that the new ``poetry`` command is available.

  3. Install the project and all its development dependencies using poetry. This also takes care of creating a new virtual environment:

    .. code-block:: bash

    poetry install --with dev,test

    This step installs PyACP in an editable mode (no build step is needed, no re-install when changing the code).

  4. Activate your development virtual environment with:

    .. code-block:: bash

    poetry shell

Testing ^^^^^^^

The PyACP test suite uses pytest_. You can run it with

.. code-block:: bash

pytest --license-server=<YOUR_LICENSE_SERVER> tests/unittests

Benchmarking ^^^^^^^^^^^^

As part of the test suite, we run some performance benchmarks. These can be run with

.. code-block:: bash

pytest --license-server=<YOUR_LICENSE_SERVER> tests/benchmarks

Additional options can be found in the pytest-benchmark documentation <https://pytest-benchmark.readthedocs.io/en/latest/usage.html>_.

NOTE: The benchmarks use the tc-netem Linux kernel module to simulate a slow network connection within a Docker container. This is available only on Linux, not on Docker for MacOS or Windows.

The benchmark results from the main branch are uploaded to https://acp.docs.pyansys.com/benchmarks.

Pre-commit hooks ^^^^^^^^^^^^^^^^

Style and linter checks are run through the pre-commit_ tool. You can run these checks with

.. code-block:: bash

pre-commit run --all-files

We also recommend installing pre-commit into your repository:

.. code-block:: bash

pre-commit install

This will run the pre-commit hooks on the changed files before every git commit. If you ever need to create a commit without running the hooks, you can skip them with git commit -n.

Documentation ^^^^^^^^^^^^^ Before generating the documentation, configure the PyACP server via the ansys-launcher, see Launching ACP <launching_server> above. If Ansys is installed the examples can directly built with Sphinx.

On Linux & MacOS:

.. code-block:: sh

make -C doc html

On Windows:

.. code-block:: batch

cd doc; .\make.bat html

The generated HTML files can be viewed with the browser of your choice.

Alternatively you can build the documentation by starting a mapdl and pydpf-composites docker container. First ensure that you have accepted the DPF Preview License Agreement by setting the ANSYS_DPF_ACCEPT_LA environment variable to Y (see DPF Preview License Agreement <https://dpf.docs.pyansys.com/version/stable/user_guide/getting_started_with_dpf_server.html#dpf-preview-license-agreement>_ ). In addition the ANSYSLMD_LICENSE_FILE environment variable needs be set to a valid license server (e.g 1055@mylicenseserver.com). Then start the docker containers with:

.. code-block:: bash

docker compose -f docker-compose/docker-compose-extras.yaml up -d

Then build the documentation with the Sphinx_ commands mentioned above.

Distribution ^^^^^^^^^^^^

The following commands can be used to build and check the PyACP package:

.. code-block:: bash

poetry build
twine check dist/*

This creates both a source distribution, and a wheel file. An alternative is

.. code-block:: bash

pip install build
python -m build --wheel
