Looking at one of the sample GRIDDESC file entries:
‘POL_HEMI’
6, 1.D0, 45.D0, -98.D0, -98.D0, 90.D0
‘HEMI_108k’
‘POL_HEMI’, -10098D3, -10098D3, 108.D3, 108.D3, 187, 187, 1
’ ’ ! end grids.
What is the significance of D0 or D3 in these entries. The specifications mentioned at https://www.cmascenter.org/ioapi/documentation/all_versions/html/GRIDS.html do not mention about D0 or D3 in this file.
I am configuring following UTM modelling grid
‘UTM_43’ !name; type, P-alpha, P-beta, P-gamma, xcent, ycent
5, 43.0D0, 0.0D0, 0.0D0, 0.0D0, 0.0D0
’ ’ ! end coords.
‘MY_DOMAIN_UTM’
‘UTM_43’, 368094.521D0, 2037825.542D0,2000.0D0, 2000.0D0,12,11,1
’ ’ ! end grids.
I am getting following error in GRDMAT:
File “GRIDDESC” opened for input on unit: 94
/data/SMOKE/SMOKE_V4.7/data/ge_dat/GRIDDESC_PMC
>>--->> WARNING in subroutine DSCGRID
Error 5010 reading coord descriptions at line 3
*** ERROR ABORT in subroutine GRDMAT
Could not get Models-3 grid description.
In case of UTM co-ordinate system what shall be the units of XORIG and YORIG, the specification mentions it as METERS.
Please Help.
