Distributed algorithms and manipulations over CGNS meshes

Maia is a Python and C++ library for parallel algorithms and manipulations over CGNS meshes. Maia introduces a parallel representation of the CGNS trees and uses ParaDiGM as a back-end to provide various functions applicable to these trees.

Getting started

Onera users

User documentation is deployed on the Gitlab pages server: https://numerics.gitlab-pages.onera.net/mesh/maia/index.html.
