Dear all,
I am getting following error. I am running ot for my 1 basin. I have created the data-sets. I have crosschecked land and atmospheric data-sets are in same dimension. but getting this error how we can resolve this please help me regarding this.

Error: (full log file has been enclosed as attachment file.)

Based on the error, you are probably using CLM3...which isn't supported. However, based on the error I'm guessing that the model is trying to map atmospheric gridcells to land gridcells and is finding more than 10 atm gridcells (11) that overlap a land gridcell, or the other way around, not really sure. You could check to make sure your atm grid lat/lons are all correct and your land grid lat/lons are all correct. You could also increase the variable mx_ovr to more than 11 and see if that fixes the problem. I think mx_ovr is defined as mxovr in atmdrvMod.F90.

Respected Sir,

I have checked the both data ATM and LAND both have same latitude and longitude. I have also increased mx_ovr form 10 to 25.

### Till 24 it is showing as same previous
nstep= 1 date= 19650201 sec= 0
ATM: attempting to read data from
/home/wcl/Anuj/CLM3_Model/Model_data/Input_basinwise/Input_basinwise/Godavari/Goda_NCEPDATA/1965-02.nc

Initializing atm -> srf interpolation .....
AREAOVR error: n_ovr= 25 exceeded mx_ovr = 24
for output lon,lat = 10 1
ENDRUN: called without a message string

### when i changed it as 25. It is showing :
Compiled CLM model successfully
executing clm model
using input model data from /home/wcl/Anuj/CLM3_Model/inputdata/lnd/clm2
Floating point exception (core dumped)
CLM run failed

what should i do please help me regarding this.
