intro story Coast / Estuary

Coast / Estuary

Coastal systems are among the most dynamic physical systems on earth and are subject to a large variety of forces. The morphodynamic changes occurring to coastlines worldwide are of great interest and importance. These changes occur as a result of the erosion of sediments, its subsequent transport as bed load or suspended load, and eventual deposition. 
 
Estuaries are partly enclosed water bodies that have an open connection to the coast. Estuaries generally have one or more branching channels, intertidal mudflats and/or salt marshes. Intertidal areas are of high ecological importance and trap sediments (sands, silts, clays and organic matter).
Within the Delft3D modelling package a large variation of coastal and estuarine physical and chemical processes can be simulated. These include waves, tidal propagation, wind- or wave-induced water level setup, flow induced by salinity or temperature gradients, sand and mud transport, water quality and changing bathymetry (morphology). Delft3D can also be used operationally e.g. storm, surge and algal bloom forecasting.

Getting netCDF as an output of Delft3D-FLOW

Hello,I'm doing postprocess Delft3D output file with Python.
I first tried to use nefis-python in Open Earth Tools, but I couldn't make it. (There were endless errors disturbing me)So now I'm trying to get netCDF file directly from Delft3D.
I put a keyword "FlNcdf = #map his dro fou#" in the mdf file, but what I got is an error :../../bin/lnx/flow2d3d/bin/d_hydro.exe: symbol lookup error:

../../bin/lnx/flow2d3d/bin/libflow2d3d.so: undefined symbol: netcdf_mp_nf90_create

The version of Delft3D is 6.02 and that of netCDF-fortran is 4.1.3.I know that the version of netCDF-fortran needs to be higher but is it the reason of that error?Because I don't want to install the newer version of netCDF if possible, since I'm so bad at GNU make. I've tried this for several days already.
Thanks in advance

Ah, and one more thing, is there any options to get outputs as both NetCDF and Nefis file?
If I add the keyword 'FlNcdf', then Delft3D-flow will generate only NetCDF file, right? But what if I also want Nefis file, besides NetCDF?
Thanks!
