error with child wind forcing file

[nma]

While using ROMS version 3.7, parent alone simulation works okay. Later, when child is added, following error was seen:-

GET_CYCLE - unable to get value for attribute: cycle_length
in variable: wind_time
This attribute value is expected to be of
the same external type as the variable.

The ncdump of wind data file looks like this:
netcdf wind {

Code: Select all

        wind_time = UNLIMITED ; // (2920 currently)

                Vwind:field = "v-wind, scalar, series," ;
                Vwind:time = "wind_time" ;
        float Uwind(wind_time, y, x) ;

                Uwind:field = "u-wind, scalar, series," ;
                Uwind:time = "wind_time" ;
....

Could anyone tell more on what is missing here to overcome this error!
Thank you.

Your cycle_length is a string: "365.". It needs to be of type double: 365. (without the quotes).
