The OpenIFS model is provided in several compressed tarfiles availale from the OpenIFS ftp site:
The model will unpack into a directory called 'oifs'.
The directory structure for the OpenIFS model and code depends on local installation requirements, number of users and so on. However, a recommended directory structure would have all source code and data organised under a single directory 'oifs'. If desired, the grib_api and FCM software could also be installed under the oifs directory but it's recommended they are placed elsewhere.
All the OpenIFS related files are available from the ftp site: ftp.ecmwf.int. If you do not have ftp site password, please email : openifs-support@ecmwf.int.
The OpenIFS distribution includes source code, datafiles and supporting software. Once logged into the ftp site you will see the following directories:
