Hi Jon,
The fact that the model is still looking for 20 (or 128) grid spacings suggests to me that you haven’t recompiled the model after making the changes in SIZE.h. The changes in that file will only have an effect when the model is compiled, not at run time.
Cheers,
Ed

Hi Martin and Malte,
Thanks for your quick responses! The specific error message from running the natl_box (and the biogeochem tutorials) was as follows:
S/R LOAD_GRID_SPACING: No value for delX at i = 11
This error message is then repeated for i=11 to i=20 where 20 was the number of grid points in the x-direction in the original setup of the natl_box tutorial.
I received the same type of error message in the biogeochem tutorial when I tried to change it from a global setup to a basin setup.
<http://mitgcm.org/public/r2_manual/latest/code_reference/vdb/names/CX.htm>
I changed the SIZE.h file to the appropriate Nx and Ny for the specified delX and delY (certainly in the biogeochem tutorial and I believe in the natl_box tutorial too). When I changed delX from delX=20*2 to delX=10*2, I altered sNx in SIZE.h from 20 to 10 to reflect this change (and made the appropriate change in sNy too). Thus, Nx= 10 = sNx*nSx*nPx .
For the biogeochem tutorial, the &PARM04 in the data file for the particular setup (global) I am using has:
delX=128*2.8125
delY=64*2.8125
and the SIZE.h file has sNx=64, sNy=32 and nSx=2,nSy=2 and nPx=1,nPy=1.
However, when I change delX to delX=24*281 in the data file and change sNx to sNx=12 in SIZE.h, and alter the size of the input files, I receive the error above repeated for i=25 to i=128.
Unfortunately, the supercomputer I am using has been shutdown today but I hope to be able to use it again asap. I therefore do not have access to the files currently to show you SIZE.h. I will try using dxspacing (and dyspacing) to see if it still gives me an error and check the natl_box experiment again when I have access.
I found that the error comes from the following MITgcm code:
$Header: /u/gcmpack/MITgcm/model/src/load_grid_spacing.F
C-- Check delX grid-spacing:
n<http://mitgcm.org/public/r2_manual/latest/code_reference/vdb/names/GU.htm> = 0
DO i<http://mitgcm.org/public/r2_manual/latest/code_reference/vdb/names/CX.htm>=1,gridNx<http://mitgcm.org/public/r2_manual/latest/code_reference/vdb/names/1QN.htm>
C- check that delX has been set
IF ( delX<http://mitgcm.org/public/r2_manual/latest/code_reference/vdb/names/VK.htm>(i<http://mitgcm.org/public/r2_manual/latest/code_reference/vdb/names/CX.htm>).EQ.UNSET_RL<http://mitgcm.org/public/r2_manual/latest/code_reference/vdb/names/CPH.htm> ) THEN
n<http://mitgcm.org/public/r2_manual/latest/code_reference/vdb/names/GU.htm> = n<http://mitgcm.org/public/r2_manual/latest/code_reference/vdb/names/GU.htm>+1
WRITE(msgBuf<http://mitgcm.org/public/r2_manual/latest/code_reference/vdb/names/AD.htm>,'(2A,I5)') 'S/R LOAD_GRID_SPACING:',
& ' No value for delX at i =', i<http://mitgcm.org/public/r2_manual/latest/code_reference/vdb/names/CX.htm>
CALL PRINT_ERROR<http://mitgcm.org/public/r2_manual/latest/code_reference/vdb/names/CVQ.htm>( msgBuf<http://mitgcm.org/public/r2_manual/latest/code_reference/vdb/names/AD.htm>, myThid<http://mitgcm.org/public/r2_manual/latest/code_reference/vdb/names/AE.htm> )
ENDIF
However, I am still unsure why I get this error message if I have changed SIZE.h correctly. In fact in the biogeochem setup I am running
(a modified version of the tutorial), changing sNx or sNy in SIZE.h to any value does not produce an error, despite keeping delX and
delY constant
(i.e.
delX=128*2.8125,
delY=64*2.8125 were not changed) which I find strange. Yet as soon as delX is changed in the
data file, the
error occurs regardless of whether the SIZE.h file is changed correctly.
Thanks in advance for your help!
Cheers,
Jon

Hi all,
I am attempting to edit the geometry in several of the tutorials (e.g. natl_box and biogeochem) to an idealised setup but I keep getting the following runtime error: S/R LOAD_GRID_SPACING.
I have altered the input files and the SIZE.h file to the appropriate domain size, although this does not appear to be the cause of the error. The error is caused by altering delX and delY in the data file to the appropriate number of grid points e.g. in the natl_box tutorial, delX= 20*2, but if I change the number of grid points (e.g. to delX= 10*2), the aforementioned error occurs!
Perhaps some other files need to be altered (in addition to SIZE.h and the input files). Any help would be greatly appreciated.
Cheers,
Jon

Hi Jon,
could you provide more details of the error messages? The S/R LOAD_GRID_SPACING has several different checks.
As a general rule, Nx = sNx*nSx*nPx should be the same as the number delX that you provide. In natl_box Nx = 20, so delX = 20*2, (twenty time 2 degrees in this case).
Whenever dx is constant, I use dxSpacing = 2 (and dySpacing) instead of delX = ?Nx?*2, this avoids having to specify the grid dimension in ?data"

Hi Jon,
It would help if you provide your SIZE.h file and the &PARM04 part of the data file that you are using.
Also: Is there anything more to the error message?
