Why the DZmin and DZmax become NaN?

#1 Unread post by zhaoqian »

When executing oceanM, some error occur and the program stop. The details are as follows:
--------------------------------------------------------------------------
Minimum X-grid spacing, DXmin = 1.39883582E+00 km
Maximum X-grid spacing, DXmax = 1.48958137E+00 km
Minimum Y-grid spacing, DYmin = 1.79470099E+00 km
Maximum Y-grid spacing, DYmax = 1.91112718E+00 km
Minimum Z-grid spacing, DZmin = NaN m
Maximum Z-grid spacing, DZmax = NaN m

Minimum barotropic Courant Number = 0.00000000E+00
Maximum barotropic Courant Number = 2.38484100E-01
Maximum Coriolis Courant Number = 2.86913724E-02

GET_NGFLD - tidal period
(Min = 4.32000000E+04 Max = 9.29494800E+04)

Will anybody tell me why the DZmax and DZmin become NaN? I created the grd file using seagrid.
I really appreciate your help!

Do you know your minimum and maximum water depths? Are they nonzero everywhere?

Thanks for your reply!
Do you mean that the depth should be nonzero in the water points and zero in the land points?
I find that in some water points,the depth is zero. This may be the reason why the error metioned occur. In order to avoiding this problem, i set the minimum depth to 5m when using seagrid to obtain depth of all grids.

The depth should be nonzero everywhere, both at sea and on land.
