[MITgcm-support] SPgrid

Wed Jul 25 04:00:07 EDT 2007

hi all,
specially to Ed,

from your last message :

Hi Pat & Riema,

Ian Fenty and I created a few curvilinear models of the Lab Sea.  One
was grid-cell-coincident with a Lat-Lon grid at the exterior and then
approximately coastline-following within the basin.  Perhaps you could
ask Ian to check his setup into the MITgcm_contrib area?  As I recall,
there were OBCS problems but I don't know whether the OBCS issues were
a direct result of the grid quantities or not.  Ian would have a better
idea.

If you want, I could create a grid that does (approximately) what you
describe above.  I'm very busy this month but in August I'll have some
free time.

Ed

did you create your curvilinear models utilize SPgrid in MITgcm under Fedora Core Linux (version 4 or 5) just like in MITgcm manual (chapter 7.5 Grid Generation)??

any other method to create curvilinear in MITgcm??

thank you,
regards
rima

Hi all,

i'd like to know about curvilinear grid format in MITgcm...anyone use curvilinear for the simulation?? can you give me a clue?? thanks

HI,

I am also interested in curvilinear coordinates in the MITgcm model.  
I want to formulate a limited area lat/lon domain with the major axis  
rotated, 20 degrees for example, relative to north with cells of  
variable size. Does anyone have any experience with Ed Hill's SPGrid  
method.

Thanks,
Pat

Hi Pat & Riema,

Ian Fenty and I created a few curvilinear models of the Lab Sea.  One
was grid-cell-coincident with a Lat-Lon grid at the exterior and then
approximately coastline-following within the basin.  Perhaps you could
ask Ian to check his setup into the MITgcm_contrib area?  As I recall,
there were OBCS problems but I don't know whether the OBCS issues were
a direct result of the grid quantities or not.  Ian would have a better
idea.

If you want, I could create a grid that does (approximately) what you
describe above.  I'm very busy this month but in August I'll have some
free time.
