[MITgcm-support] Questions about EXF and OBCS

[han]

Dear MITgcm community,I am running a case with open boundaries all around, with a model resolution of 0.03 and output every 3 hours. When I don't add boundary conditions (OBCS),  the program can run successfully. However, once the boundary conditions are added and all other data  remains unchanged, the program displays the error  'STOP ABNORMAL END: S/R EXF_CHECK_RANGE ' after running for a period of time. Nevertheless, whether boundary conditions(OBCS) are added or not, the model will appear obvious deviations from the third hour (the data differed significantly from the normal values). I'm not sure what the problem is, or what methods can I try to solve this problem?
My EXF uses swdown, lwdown, precip, atemp, aqh, uwnd and vwnd data, and ensures that each value is within the required range.
After adding the boundary, EXF_CHECK_RANGE is displayed, and the following content will be shown in STDOUT


cg2d: Sum(rhs),rhsMax = 2.42073525314462E+06 1.99340964002214E+01
EXF WARNING: hflux out of range for bi,bj,i,j,it= 1 1206 8 40334 0.160016382290418D+04
EXF WARNING: If you think these values are OK
EXF WARNING: then set useExfCheckRange=.FALSE.


I would appreciate any suggestions.


Best regards,
Han
