NAG library on RACC2<\/h2>\n

The NAG license is available only to the Department of Meteorology<\/strong>. To get access, please raise a ticket asking for a copy of the license file (\/software\/applications\/NAG\/nag_key.txt) to be placed in your home directory. This process will also allow us to record license usage, so please always request access via a ticket and do not share the license file, even within the Department.<\/p>\n

You will need to manually export the variable with the location of the license file.<\/p>\n

There is only one version, Mark 31. Module files are not provided because it would just make it more confusing. Please source the supplier’s configuration script which will set up the environmental variables according to the selected options. Please refer to the supplier instructions at https:\/\/support.nag.com\/content\/downloads-nag-library-nll6i31dbl<\/a>, or see the following example.<\/p>\n
