cpp_cgns (C++/CGNS) offers a mapping of CGNS trees into a C++ in-memory representation, plus utilities for manipulation of C++ CGNS trees.

The documentation can be found here

Dependencies

cpp_cgns is a C++ library. It depends on std_e (provides generic algorithms and multi-dimensional array facilities). Python interoperability (cpp_cgns/interop folder) requires Python and Numpy.

Build and install

1. git clone https://gitlab.onera.net/numerics/mesh/cpp_cgns
2. cd cpp_cgns
3. git submodule update --init (needed to retrieve submodules)
4. Use cmake to configure, build and install
