Suite copy

Hi there,

I copied one of my working suites using the command: “rosie copy u-dn534”. However, I found that the newly generated suite, u-dn814, failed to run. When I ran “fcm diff -g”, I noticed numerous differences in the app/um/rose-app.conf file. This was unexpected, as I assumed all settings would remain identical to the original suite.

I suspect this issue might be related to the fact that I copied a UKCA suite rather than a UM suite, but I am not entirely sure. Additionally, I am unsure how to copy an entire suite, including all UM settings, to a new one. Any guidance on this would be greatly appreciated.

Best,
Xin

Hi Xin,

rosie copy <suiteid> takes a copy of the suite as it is in the MOSRS repository. You have uncommited changes in your suite directory ~/roses/u-dn634.

ros@puma2$ cd ~emxin/roses/u-dn634
ros@puma2$ fcm status
M       app/um/rose-app.conf
M       rose-suite.conf

These changes will not be picked up rosie copy until they are saved (fcm commit) to the MOSRS repository.

rosie copy <suiteid> is the correct command; it copies an entire suite to a new suite id.

Regards,
Ros

Hi Xin,

To avoid any confusion - UKCA does not yet run in stand-alone mode - (apart from a highly prescribed Box model). All the model configurations (suites) available currently are Unified Model based - built using source files from UKCA (and JULES, SOCRATES, etc ).

Hope that helps, M

H Ros and Mohit,

Thanks for the help and clarification. Yes, I did not save the changes made in the old suite (u-dn634) before copying. After I saved the changes and made a new copy, it improved. However, there is a new problem: after I updated the intial file in the new suite copied (u-dn581), and run it, it showd an empty file:
-AINITIAL_FILE=‘’
I have “fcm commit” the suite before run it. Note that the file path to the intial file was correctly updated in the suite.

Best,
Xin

Hi XIn,

I’m not sure what you mean. When I look in ~emxin/roses/u-dn851/rose-suite.conf I see:

AINITIAL_FILE='dn634a.da20200301_00'

Cheers,
Ros.

Hi Xin,

You seem to have inadvertantly removed the file while changing the run start . See snapshot of the diff (Red =previous, Green = after change).

It might also be better to copy the proposed ainitial file to another location, as this will be lost if you delete the u-dn634 suite.
