Notice: these files contain consistent synoptic data sets for the staggered computational grid and can therefore be used as initial conditions for a subsequent simulation; because they are defined on a staggered grid they cannot be used in conventional postprocessing programs.

Notice:

dictionary-file hyd_untrim_dico.dat, normally present in directory $PROGHOME/dic/, will be automatically read by the application program in addition to the user-specified input file.
furthermore the following configuration files stored in the directory $PROGHOME/cfg/ are eventually automatically read by the program:

all_2d_water_level.dat
all_2d_velocity.dat
all_2d_salinity.dat
all_2d_temperature.dat
all_2d_suspended_load.dat
all_3d_velocity.dat
