Dear all,
As I have found out, netCDF should be built with HDF5 support to be able
to benefit from compound types. I installed HDF5 and recompiled netCDF
with HDF5 support and now I can benefit from compound types. First, I
create the file to be written with:
*nf90_create(FILE_NAME, NF90_HDF5, ncid)*
Up till here everything is OK. Then I define the compound type with:
*nf90_def_compound(ncid, sizeof(ep_data), "ecopath_data", typeid)*
where it gives the error: "NetCDF: HDF error STOP Stopped". If I further
add the below line which defines a field for the compound type; without
resolving the former error:
*nf90_insert_compound(ncid, typeid, "biomass", 1, field_typeid)*
The error changes to " NetCDF: Not a valid data type or _FillValue type
mismatch. STOP Stopped." All the errors come as runtime errors and the
code compiles flawlessly. I am wrestling through the documentation but
many commands miss explanation, e.g. *NF90_FILL_REAL* (to fill
_FillValue), *NF90_PUT_VARA* (to flush array into the defined compound
field) etc.
I would be glad if someone can help me on the matter,
Regards,
Ekin

Dear all,
This time around I have come up with a problem concerning compound
types. I scripted a FORTRAN subroutine to write data in compound form
into a .nc file and it compiles perfectly, however, it gives exactly
the error "Unknown error" when I run the model calling the ncwrite
function after model run once is completed. My FORTRAN subroutine file
is attached. It gives the error when it reaches the line with
"nf90_def_compound" function. My netCDF version is 4.1.3 and fortran
compiler is gfortran 4.4.5. I had compiled netCDF with
--disable-netcdf-4 option. Could this be the cause of the problem?

Dear all,
I have come up with an answer to my question, that is, user-defined
"compound types" in netCDF. The compound types are not very well
documented under FORTRAN API, however, section for C API gives also
an example where one can develop on for FORTRAN. If you are also
interested please see:

Thank you...

Dear all,
I am quite inexperienced in using netCDF FORTRAN API and netCDF
format in storing data. Currently I am struggling on a problem. I
have user derived data types in FORTRAN with multiple components,
i.e. fields, such as:
ep_data%biomass
ep_data%pob
....
ms_data%biomass
ms_data%age
...
Is there a way to envelope the fields (after % sign) under e.g.
"ms_data" and "ep_data" defined types when writing in a single
netcdf file so that the "biomass" field of "ms_data" does not
interfere with the "biomass" field of "ep_data" while reading it
from the .nc file? I would be glad to hear if you have suggestions
on the matter.
Regards,
