DataAssimilationProcesses; WaterProperties. ERR40

Postby philippe.maron@univ-pau.fr » Tue Apr 05, 2011 14:05

Hi,
I try to do an assimilation data in the second level of a 2D model.
The first model is forced by tides level Jauges from FES2004.
In the second level I would like to assimilate waterproperties from a mercator files.
First, I did a 2D mercator files with HDF5Extractor and I use this file as MER_C3_V1.2.hdf5
In the Waterproperties_1.dat, I put :
ADV_METHOD_H : 4
TVD_LIMIT_H : 4
ADV_METHOD_V : 4
TVD_LIMIT_V : 4
REFERENCE_DENSITY : 1026.72546
<beginproperty>
NAME : temperature
UNITS : C
DESCRIPTION : salinity initial condition from mercator solution
DEFAULTVALUE : 14.
ADVECTION_DIFFUSION : 1
DATA_ASSIMILATION : 1
DISCHARGES : 0
BOUNDARY_CONDITION : 4
SUBMODEL : 1
TYPE_ZUV : z
INITIALIZATION_METHOD : HDF
FILENAME : ../GeneralData/MER_C3_V1.2.hdf5
OUTPUT_HDF : 0
<endproperty>
... idem for salinity

and in Assimilation_1.dat
<beginproperty>
NAME : temperature
UNITS : C
DIMENSION : 2D
TYPE_ZUV : z
<<begin_field>>
DEFAULTVALUE : 14
TYPE_ZUV : z
INITIALIZATION_METHOD : HDF
FILE_IN_TIME : HDF
FILENAME : ../GeneralData/MER_C3_V1.2.hdf5
<<end_field>>
<<begin_coef>>
DEFAULTVALUE : 1e9
TYPE_ZUV : z
REMAIN_CONSTANT : 1
INITIALIZATION_METHOD : SPONGE
SPONGE_OUT : 1e5
<<end_coef>>
<endproperty>
... idem for salinity


At last I obtain the error message

---------------- INTERFACE SEDIMENT-WATER -----------------

Num of Properties : 0

-------------------------- MOHID -------------------------

Running MOHID, please wait...

Hi,

The error is related with the definition of the relaxation coefficients.
The SPONGE option is relatively new in MOHID. Is the executable you're using compliant with this option? It seems to that you're executable version is old.

Hope this helps. If not, send me WaterProperties and Assimilation input files and the date of the executable.

Best regards,
Luis
