<p class=MsoNormal>Hi all,<br>
<br>
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: <em>Flerchinger
USEd</em> in NEW <em>version</em>. 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.<br>
Any suggestions?<br>
<br>
Thank you in advance<o:p></o:p></p>
