Hello my name is Ardie,
First of all, thanks for the time for reading my email,
By the way, I am doing a sensitivity test to PBL schemes using the WRF model, with the Cumulus Parameterization schemes set to Betts-Miller, I am using the WRF model version WRFV3.0.1.1 , I am hoping someone can enlighten me on this error (after running for ~10 hours and the model stopped abruptly) and how to solve it:
RIB never exceeds RIC, RIB(i,kte) =  NaN             THETAV(i,1) =
 NaN             MOL= NaN             TCONV =   9.0186588E-02  WST =
 NaN             KMIX =            1  UST =  NaN             TST =
 NaN             U,V =  NaN            NaN             I,J=          66

The PBL scheme I am using is ACM2 PBL (Asymmetric Convective Model with non-local upward mixing and local downward mixing),
Might it have something to do with the sf_sfclay_physics? which i used the Monin-Obukhov scheme (option 1), I also don't understand the difference between the option 1 and 2 of the sf_sfclay_physics scheme (as both are stated using the "Monin-Obukhov scheme")

 regards,
Wan Ahmad Ardie
