@ZHHisme have you checked CFL and your time steps are defined according to it? |

Why my WW3 result's WAVE HEIGHT overflows normal value???
At the begining, HS seems normal, but about 1 hours later, the HS goes wrong... If anyone could figure the questions?? Thanks.

$ ----------------- FOR SMC GRID ONLY ---------------------------------$
$ SMC output type:
$ 1 = Flat points file (1D sea point array)
$ 2 = Regular gridded (2D lat/lon array over region)
$
$ 1
$
$ For SMC output, the IX/IY range line is replaced with a domain
$ lat/lon range and
cellfacparameter for SMC type 2 output.$ First/Last lat/lon can be set to -999.9 to use edge of SMC grid.
$
$ For SMC type 1 output, only those points within the specified
$ lat/lon ranges will be extracted:
$
$ first_lon, first_lat, last_lon, last_lat
$
$ For type 2 output, the range is used in conjunction with a fifth
$ integer
cellfacparameter to specify the regular output grid$ to area average the SMC grid to. In this case, the output grid will
$ be aligned to nearest largest SMC grid points within the selected
$ region. Therefore, the output grid start and end lat/lons may differ
$ slightly from what is requested. In order to obtain a fully populated
$ regular grid the extents specified should encompass the SW corner of
$ the bottom left cell, and NE corner of the top right cell required.
$
cellfacis an integer value that selects the target grid cell size$ as multiple of the smallest SMC grid cell. It must be a power of 2.
$ e.g. 1 = highest resolution, 2 = half resolution of smallest cell,
$ 4 = 1/4 res of smallest cell, etc.
$
$ first_lon, first_lat, last_lon, last_lat, cellfac
$
$ Example: Extract high resolution data for U.K.:
$
$ -13.50 46.85 5.50 61.0 1
$
$
$ ---------------- FOR NON-SMC GRIDS --------------------------------- $
$ IX, IY range:
1 1000000 1 1000000
$
$ For each field and time a new file is generated with the file name
$ ww3.date_xxx.nc , where date is a conventional time indicator with S3
$ characters, and xxx is a field identifier.
