Welcome to the Unified Model Code
This Trac instance is associated with the svn://puma/UM_svn/UM repository.
This is the home of the Unified Model Code from UM version 7.x. The trunk of the repository contains 'pure' Met Office code, mirroring the trunk of the Met Office repository. A UM version equates to a specific revision of the trunk and is identified by an FCM keyword (E.g vn7.1).
Note that you need to be logged in to view any other pages of the wiki or to browse the source code.
If you've never used the UM with FCM before then we strongly recommend that you first work through the UM Tutorial first.
Write access to the subversion repository and privileges to create/modify Trac tickets and wiki pages are given to authorized users only. Please contact r.s.hatcher (at) reading.ac.uk to register your username.
Before you can work with the UM there are several things you must have set up first. Please read the SettingUpYourEnvironment page.
It is also recommended that you read the FCM Hints and Tips page.

All UMUI jobs, except those being run on MONSooN, must include the NCAS configuration branch which contains all essential non-scientific code changes to enable the UM to run on the NCAS HPC. If you don't include this branch the job will NOT work.
Make sure the following branch is in the "User Modifications" Table in window FCM Configuration --> FCM Options for Atmosphere and Reconfiguration and place a "Y" in the last column to activate it. Please do not specify a revision number for this branch so that you can be sure to pick up all the essential fixes available.
where <um_version> is the version of the UM you wish to use e.g. 7.1
