Hi,
have you already tested this: NETCDF CLIENT 2016 ?
This program converts structured grid NetCDF and GRIB2 files with CF convention (http://cfconventions.org) to MIKE DFS files and vice versa.
Other NetCDF files which are non-compliant with CF convention will not work, however additional modifications are possible to enable the conversion of non CF convention NetCDF files to DFS files on a request basis. For such requests, please contact mike@dhigroup.com.
This tool is developed for MIKE by DHI 2016.
You may download it from:
https://www.mikepoweredbydhi.com/download/mike-by-dhi-tools
Maybe, if you contact DHI, they could support you also with MIKE2014.
