A problem about the values of Fdx,Fdy,Fdz

[wjy]

In the file of float.in,what the value of Fdx,Fdy,Fdz should be made? and why? Thank you!!!!!!!!!!

[kate]

Only one can be different from zero at a time, including Fdt. They are for a group of floats in a line - in i,j,z, or time. Try it, you'll see.

Thanks for you advice,i fllow what you have said.But,in the destination file of
destination file, there is no value of XGRID,YGRID and ZGRID.Can you tell me the mistake i had made? thank you.

Is it running at all? Giving an error message? I don't know why you'd end up with a floats file and no float positions.

[wjy]

It's running all the time with no error,but there is no value in the destination file.
this is my setting in float.in :
Lfloats == T
FRREC == 0
NFLOATS == 5

POS = G, C, T, N, Ft0, Fx0, Fy0, Fz0, Fdt, Fdx, Fdy, Fdz

1 1 1 5 0.0d0 118.039d0 24.432d0 16.0d0 0.d0 0.05d0 0.d0 0.d0
Is there some probrem?
I want to know if the codes of wrt_floats.F, and other *.f90 about float need some modification.
Would you give me some advice? Thank you.

Did you #define FLOATS? Are you getting a floats file at all? It should be a separate output NetCDF file.

[wjy]

I have #define float in *.h,and the roms creat the output NetCDF file.
I use ferret to see the result in output NetCDF file.
but the result is:
yes? list/l=6666 LON
VARIABLE : longitude of floats trajectories (degree_east)
DATA SET : ROMS Study In Taiwan Strait(Salt
FILENAME : ocean_flt.nc
SUBSET : 5 points (X)
TIME : 05-JUN-2000 15:05
1 / 1:....
2 / 2:....
3 / 3:....
4 / 4:....
5 / 5:....
"l" is timestep.
when l=1,the result is:
yes? list/l=1 LON
VARIABLE : longitude of floats trajectories (degree_east)
