Description

Running with the CASIM scheme and Shipway microphysics causes a crash on the Monsoon Cray system.

I get an error in my .leave file of

I believe you must be one of the first users of CASIM - at this stage I really think your best bet is to contact its owners.

In general, please supply more information with such queries; job id, location of leave file etc.

Hi Grenville
Yes that is true. There are only a few of us using it. The reason I am submitting tickets is basically only because that’s what the FCM tutorial tells me to do before I create a branch to work on something. I thought that the idea was that the tickets were a means of documenting the branches. However if that isn’t the case I will stop creating tickets and apologies for creating noise - I'm still trying to work out best practice for this, and it did fee a bit odd creating a ticket which gets reported to you for my branches.

Hi Phil,

If you wish to create tickets as a means of documentation for your branches, this needs to be done on the UM Trac (http://puma.nerc.ac.uk/trac/UM) (likewise on the NEMOCICE Trac for NEMO/CICE branches) and not this Trac which is the UM Helpdesk. It is not compulsory to create tickets when you create a code branch, it is just a facility that is available to you should you wish to use it.

Regards,
Ros.
