pychrono-examples (PyChrono 10.0)

A collection of ready-to-use PyChrono examples, targeting PyChrono 10.0. This is the 10.0 line of pychrono-examples-9.0: the curated examples were ported from 9.0 to the 10.0 API and verified by running them against a real PyChrono 10.0 install.

Each top-level folder focuses on one class of models (e.g. vehicle, mbs, fea, sensor, robotics, ros); a misc subfolder holds assorted models.

Status

Every example in the main tree has been verified on PyChrono 10.0 (imports, constructs, and advances the simulation a few steps headless without error). Examples that still need updating for 10.0 live under wip/. See STATUS.md for the full list and the reason each wip/ example is pending (most are FEA demos affected by the 10.0 visualization API change).

Running an example

# In a PyChrono 10.0 environment, e.g.:
#   conda create -n pychrono -c conda-forge python=3.12
#   conda install -n pychrono -c projectchrono -c conda-forge pychrono
conda run -n pychrono python vehicle/hmmwv/hmmwv.py

Most examples open an Irrlicht visualization window. They use the Chrono data shipped with PyChrono, so no extra assets are required beyond what each example folder contains.

Porting and verification tools

tools/ holds the machinery used to produce and check this repo, so it can be re-run against future PyChrono releases:

• tools/migrate.py - the 9.0 -> 10.0 mechanical migration porter.
• tools/verify_runner.py / tools/verify_all.py - run examples headless (visualization stubbed, a few steps) and report pass/fail.
• tools/_verify_report.json - the latest verification results.

conda run -n pychrono python tools/verify_all.py            # verify everything
conda run -n pychrono python tools/verify_all.py vehicle    # verify one folder

Contributing

Pull requests that fix a wip/ example for 10.0 (move it into the main tree, verified) or add new models are very welcome.
