Info

The OpenIFS models run on a variety of Unix based systems: Unix/Linux, Mac OS X. There is no support for running under Windows.

Common requirements

The OpenIFS model, Single Column Model (SCM) and the Offline Surface Model (OSM) (HTESSEL) all require the following in order to build and run. Most of these should be available as standard on Unix/Linux systems:

...

grib-api/eccodes  - the grib-api library or its replacement eccodes library and accompanying set of commands for working with and manipulating GRIB files. GRIB is the file format used as input and output for OpenIFS.  See the grib_api for OpenIFS install page for more details on how to build grib_api for the OpenIFS models. If using eccodes, some model code changes for older OpenIFS versions may be necessary. See install page for more details.

.

Perl modules required

Software called FCM is used to compile the model. FCM is provided with OpenIFS. However, note that it may need additional Perl modules installed. The most likely missing modules are: XML::ParserCheck and Time::Piece.
