Salinity and temperature open boundary conditions from global model (HYCOM) into 3D MOHID Hydrodynamic model

Hello, i'm configuring a MOHID 3D hydrodynamic model for an estuary. I want to introduce salinity and temperature from global model HYCOM as open ocean boundary condition (it is already configurated with sea level from HYCOM+FES). The HYCOM solutions are 2D and my grid is 3D with 10 layers. So, the way i try to do it was, first i converted the HYCOM solution to 10 layers (i just repeat each layer) and then i converted it to HDF5 file. I started imposing only salinity boundary condition and my water properties file looks like this (only the salinity section):


<beginproperty>
NAME : salinity
UNITS : psu
DESCRIPTION : No description was given.
INITIALIZATION_METHOD : HDF
FILENAME : ../data/salinity_temperature_RPtideV3.hdf5
DEFAULTVALUE : 38.
!DEFAULTBOUNDARY : 38.
REMAIN_CONSTANT : 0
!BOUNDARY_INITIALIZATION : EXTERIOR
BOUNDARY_CONDITION : 2
SUBMODEL : 0
OLD : 0
FILE_IN_TIME : HDF
FILENAME : ../data/salinity_temperature_RPtideV3.hdf5
SCHMIDT_NUMBER_H : 0.2
SCHMIDT_COEF_V : 0.2
ADVECTION_DIFFUSION : 1
DISCHARGES : 1
DISCHARGES_TRACKING : 0
VERTICAL_MOVEMENT : 0
SURFACE_FLUXES : 0
BOTTOM_FLUXES : 0
DATA_ASSIMILATION : 0
PARTITION : 0
WATER_QUALITY : 0
TIME_SERIE : 1
BOX_TIME_SERIE : 0
OUTPUT_HDF : 1
STATISTICS : 0
<endproperty>

I've already check that the hdf5 file is correct, but when i run the model it shows errors like this for many grid cells

Property : salinity
Negative initial concentration in cell 61 322 1
New concentration = 33.9384472301960
CheckFieldConsistence - ModuleWaterProperties - WRN02

and at the end it says 

Property salinity solution is read from file.
CheckOptionsSolutionFromFile - ModuleWaterProperties - ERR01

Any idea about why i'm getting this error or if there is another way to impose a time serie salinity and temperature condition in each open ocean boundary cell??

sorry for my english, i hope i was clear with my problem, I would appreciate any suggestion,
