[MITgcm-support] internal wave verification: problem with output for delX

[Jeremy Miller]

Hi Martin,
Thanks for your reply. Your suggestion did cure the problem of all the delX
values being read in as '0'. Thanks.
But now running the code (using ./mitgcmuv > output.txt ) gives me the error

SOLUTION IS HEADING OUT OF BOUNDS: tMin,tMax= -7.361E+22  5.849E+22
  exceeds allowed range (monSolutionMaxRange=  1.000E+03)
MON_SOLUTION: STOPPING CALCULATION at Iter=        10
S/R ALL_PROC_DIE: ending the run
STOP ABNORMAL END: S/R MON_SOLUTION, stops due to EXTREME Pot.Temp

I have attached the python script used to generate the data again.

Best
Jeremy
