Download the current stable version

Links to download Cloudy

You can download Cloudy from the DownloadLinks page.

You can then go on to the next step, EditPath.

The rest of this page goes into some detail about the directory structure and different ways to get the download. This can be skipped if you got what you need from the DownloadLinks page.

More on the downloads

Many versions of Cloudy exist on this site. Only the current stable version should be used in publications.

This page describes several ways to download the code and its documentation. A complete download will include the source, a large set of atomic data files, the test suite that is used to validate the code's behavior on your system, the test suite output, and the code's documentation Hazy. Each will be in its own directory and each directory has a readme file that describes the contents of that directory in greater detail.

IMPORTANT: Do not install the Cloudy files in a directory that contains an earlier version of Cloudy (or any other code). Delete the old installation first, or use a completely new location. If you don't start with an empty directory, the compilation process may get confused by source files from the old distribution leading to strange errors. Also the test suite may produce spurious errors if left-over scripts are executed from the old Cloudy distribution.

IMPORTANT: Do not install the Cloudy files in a directory with a name that contains spaces, nor in a subdirectory of such a directory. In other words, the path to the Cloudy files should not contain any spaces. Most notably, Cygwin users should not install Cloudy in the "Program Files" directory. The Cloudy scripts will not work correctly if spaces are present in the path.

The files that you download will have version numbers included in their file names. The first digits of the version number indicate the year of release. For example, C08 was released in 2008. The next two numbers are 00 for the initial release and will increase if releases with minor changes are posted.

When new versions of the code are released they will be announced on the Cloudy discussion board. You can join that group to get emails of announcements.

The download will come as a tar'd and gzip'd archive that should be opened keeping the directory structure intact. Explode the archive with "tar -xfz name.tar.gz". On Windows you will need winzip or a compatible program.

After the download is exploded you will have the following directory structure:

Ways to get this download

The DownloadLinks page gives links to the current version.

You can get the files directly from its subversion repository. To find out all the available releases, type the following command

svn list svn://

The highest number will be the most recent release. You can also find the name of the current stable version from the NewOnThisSite page. Next you obtain the release of your choice by issuing the command.

svn export svn://<name of version>

where "c<name of version>" should be the appropriate release you picked from the "svn list" output.

See the Subversion book for more details on how to use the svn command.

Old versions of the code

This directory contains all downloadable files, including output from the test suite on several platforms and older versions of the code.

Next step: EditPath - edit the file path.cpp to point to the data files.
