Description: Computational fluid dynamics data container.
Long Description: The CFD General Notation System (CGNS) provides a general, portable, and extensible standard for the storage and retrieval of computational fluid dynamics (CFD) analysis data. It consists of a collection of conventions, and free and open software implementing those conventions. It is self-descriptive, machine-independent, well-documented, and administered by an international steering committee.

If you haven't already installed Darwin Ports, you can find easy instructions for doing so at the main Darwin Ports page.
Once Darwin Ports has been installed, in a terminal window and while online, type the following and hit return:

%  cd /opt/local/bin/portslocation/dports/cgnslib
%  sudo port install cgnslib  
Password: 

You will then be prompted for your root password, which you should enter. You may have to wait for a few minutes while the software is retrieved from the network and installed for you. Y ou should see something that looks similar to:

--->  Fetching cgnslib
--->  Verifying checksum for cgnslib
--->  Extracting cgnslib
--->  Configuring cgnslib
--->  Building cgnslib with target all

--->  Staging cgnslib into destroot

--->  Installing cgnslib

- Make sure that you do not close the terminal window while Darwin Ports is working. Once the software has been installed, you can find further information about using cgnslib with these commands:

%  man cgnslib
%  apropos cgnslib
%  which cgnslib
%  locate cgnslib
