Hi,

I'm trying to simulate the T,S,U,V in the hypersaline lake, where i'm using
field observation of Temperature and Salinity as initial conditions
(hydrogThetaFile=temp.bin and hydroSaltFile=salt.bin ). In this study area
temp and salinity observation are high values are recorded for supposed
salinity ranges from 30-80ppm. The model is blowing at the second time step
using this data (error is nan values ).

I Think as similar for forcing fields  useExfCheckRange=True/False (check
range of input fields and stop if out of range) has to be set for
hydrogThetafile and hydroSaltFile. But, for PARM05 to check the range of
initial conditions is not available. for this case how to set for higher
values.

The model runs without any error found, while the field observation data is
modified and maintains the range for temp (25-29) and salinity(33-38).
