Set time_step in namelist.input 150 or 180. Your setting of 27s is too
short for your case.

Hi all,

I am using WRF V3.0 for the simulation of a heavy rainfall case. Three
nested domains have been defined with a grid spacing of 27, 9, and 3 Km
respectively. YSU BL scheme and NOAH LSM have been used while the KF
cumulus param has been used for the first two domains. The time step was
set to 27 s (with a time step ratio of 3 for each nested domain) and the
inegration period was 96h. When i use the PLIN (mp=2) microphysics param
the model runs without problems. But if i choose the WSM6 (mp=6) the run
stops and I get this error message: Flerchinger USEd in NEW version.
Iterations= 10 . Searching it on the internet i saw suggestions that
this message is related to a violation of the cfl criterion. I tried
smaller timesteps (18 and 9 s), changed the size of the domains and the
vertical resolution but this error keeps coming back in later timesteps.
Any suggestions?

Thank you in advance
