Part 1: What is the CGNS format and how to get started
The CGNS file format is one of the most powerful file formats there is when it comes to CFD applications and the first one each CFD developer should study in depth. It can store both structured and unstructured grids and the corresponding flow solution and has additional support to store information pertinent to your CFD Read More
