blowing up on nested grid

[jitraporn13]

Dear All,

I’m trying to run nested grid, It blows out since the beginning
I noticed on DZmax and courant number on Grid02:
Minimum X-grid spacing, DXmin = 1.00000000E-40 km
Maximum X-grid spacing, DXmax = 5.12482819E+00 km
Minimum Y-grid spacing, DYmin = 1.00000000E-40 km
Maximum Y-grid spacing, DYmax = 5.01111003E+00 km
Minimum Z-grid spacing, DZmin = 5.60947682E-02 m
Maximum Z-grid spacing, DZmax = 4.64003949E+35 m

Minimum barotropic Courant Number = 1.23681706E-03
Maximum barotropic Courant Number = 1.40071410E+56
Maximum Coriolis Courant Number = 1.00000000E+37

When I checked Grid02 by itself. It works well. Please give me some suggestion.

Bests,
