CGNS stands for CFD General Notation System. It is a general, portable, and extensible standard for the storage and retrieval of CFD analysis data. It consists of a collection of conventions, and free and open software implementing those conventions.

The CFD General Notation System (CGNS) provides a general, portable, and extensible standard for storing and retrieving computational fluid dynamics (CFD) analysis data. It consists of a collection of conventions, and free and open software implementing those conventions.

2023年2月1日 · 应用介绍： “核谐号cgn”是一款智能楼宇设备设施云服务管理平台，用户可通过该平台进行快速接单、维修、巡检、维保等完成一系列无纸化的流程操作，遇到紧急问题，可以快速上报的机制。

CGNS作为流体计算领域一个非常重要的数据格式或者说是数据库，从事这方面工作的科研人员有必要对其加以了解。 由于国产CFD开源软件 OneFLOW 大量使用CGNS作为核心的数据结构，并不断在演化迭代的过程中，这样，借这个机会正好将重构的过程形成文档，做到一举多得的效果，这也是敏捷开发的应有之义。 当然，本文的这种做法实际上从概念上已经超越了敏捷开发，也就是类似具备知识知识库和知识自动化的效果。

The CGNS file format is to CFD what PDF files are to written text documents. It is an exchange format that is supported by most CFD solvers. If you have your mesh stored in a CGNS file, chances are you can read it with your solver of choice (unfortunately, not OpenFOAM, though, but who knows, it may change in the future).

CGNS4m, formerly known as mexCGNS, allows you to access virtually all the functionalities provided by the serial API of the mid-level library of CGNS (a.k.a. cgnslib) with the convenience of MATLAB or GNU Octave.
