Dear all,
I am currently doing simulations at 20KM resolution. I had done some simulation before and successful runs completed with the following $timeparam settings
&timeparam
radfrq = 30.,
abemh = 18.,
abatm = 120.,
dt = 60.,
I am currently continueing with sensitivity test over the same domain and period. I have only modified LANDUSE file in Terrain directory and changed FUDGE_LND/FUDGE_LND_s
in domain.param. with the same &timeparam settings as in above, the runs results are NaN as shown in a section below;
maximum time = 121.000 days.
time step = 60.00 seconds
dx = 20000. meters
grid points (x,y) = (154, 78)
number of levels = 18
constant hor. diff. coef. = 0.10000E+05 m*m/s
maximum hor. diff. coef. = 0.10417E+06 m*m/s

QN: What is wrong with my current settings, any idea please.
Do change of Makefile in the Main directory affect time step settings.
Really appreciated!
