Hello all
I am trying to simulate fog in WRF-Real and made it successfully with different PBL schemes (eg, YSU, MYJ, ACM2, QNSE) except MYNN2.5 or 3. I used the same name list and same time step for all PBL schemes. But I'm facing problems with MYNN2.5 or 3 only. Can anyone help me out with your valuable experience / suggestions :)

. Its control run/ I haven't modify the source code
. I used dzstretch options to increase verticle levels below 1000m
. also, I tried the small timestep like 4,6,8 still simulation not finished

I am attaching my namelist
