Errors in Reconfiguration Stage

Description

Hi,

with regards to this ticket http://cms.ncas.ac.uk/trac/UMHelpdesk/ticket/731#comment:11 I was still wondering about

"I believe we can rule out the warning on volcanic forcing as a possible error, it seems

"UM ERROR (Model aborting) :

Routine generating error: Bi_linear_h Error code: 10 Error message:

over-writing due to dim_e_out size"

and possible changes involving tr_vars (they could also be related) may be a problem.

Do you know if the apparent changes to tr_vars could be causing the model to abort with such an error?"

I'm looking into the merging changes, however, I've been advised that these may not be so much a problem (I'm looking into them though). If it is known what causes this "Bi_linear_h" error, and say what file, then perhaps I could isolate the problem. Currently I'm unsure about what may give such errors. Do you know of anything that may cause such errors? As I mentioned I have seen similar problems in this ticket http://cms.ncas.ac.uk/trac/UMHelpdesk/ticket/286 but have no reason to suspect it may the land sea mask that is causing the problem.

Thanks,

Simon

Hi Simon,

For this particular error, there are a large number of causes so focussing on the error is not helpful. In general UM errors can be divided into a number of causes,

  • confusion over the setup
  • bad initial data
  • errors in code/modelling

We have already eliminated the first two issues. As I have said, you need to establish, when HECToR is running properly, the revision of the Improved_Volc branch that works. There are three critical revisions,

  • 6395 - creation
  • 6932 - merged
  • 7917 - current

and we have established that the last doesn't work. So I would recommend testing the first two. Just copy the job, change the revision number of the branch in FCM Config > FCM Config Optional Mods and run them.

As regards tr_vars, I have only very briefly examined the changes and suggested areas where I was suspicious. I am not claiming that these are wrong. But you need to be confident that they are right.

Regards,

Willie
