Python API Reference

This section documents the DNDSR Python package, which wraps the C++ core via pybind11 and provides high-level utilities for mesh I/O and solver setup.

The reference is generated from a combination of:

• .pyi stub files (produced by pybind11-stubgen from the compiled modules)

• Pure-Python wrapper docstrings

• sphinx.ext.autodoc runtime introspection (when the package is importable)

Note

To build this reference with full autodoc support:

1. Build and install the pybind11 modules: cmake --build build -t dnds_pybind11 geom_pybind11 cfv_pybind11 eulerP_pybind11 -j32 cmake --install build --component py

2. Install the package: pip install -e .

3. Build docs: cmake --build build -t docs

Overview by Module

Module	Purpose	Key Classes / Functions
DNDSR.DNDS	MPI, arrays, serialization	MPIInfo, Array, ArrayPair, SerializerFactory
DNDSR.Geom	Mesh I/O and topology	UnstructuredMesh, UnstructuredMeshSerialRW, ElemType, read_mesh, prepare_mesh
DNDSR.CFV	Finite volume and reconstruction	FiniteVolume, VariationalReconstruction, ModelEvaluator
