I have a wet-bias (high precipitation) in the second domain (urban).
WRF 4.5
d01 = 100x100
d02 = 111x111
15km x 3km
GF,YSU,Thompsom
cu_physics turned off for 3-km domain
sf_surface option = 2, noah lsm
I activated shcu_physics for 15-km domain to control heat/moisture buildup, and it lowered the numbers.
I still have high precip over Oct-Nov months.
One suggestion was to activate
sf_urban_physics for 3-km domain
-- however, simulation stopped on its own
Any suggestions/corrections to get sf_urban_physics option to work.
Most test runs stopped at time step of 6 hours (GDAS input interval)

Without sf_urban_physics, the three lines above, the simulation works for the set full period.
