The diagfi.def file is an optional file that is read by the GCM at run time. If it is present then it will dictate which fields will be included in the diagfi.nc output file.
A clarification: generating the diagfi.nc output file is only possible when running with the lon-lat (LMDZ.COMMON) dynamical core (or in 1D), with the Generic or Mars physics packages.
diagfi.def format
Each line of this ASCII file should contain the name (case sensitive!) of a variable to output.
Note that the variable name to use is the one set in the code when calling the write_output routine. e.g.
call write_output("temperature","atmospheric temperature","K",zt)
implies that the variable temperature can be outputted in diagfi.nc

- If there is no diagfi.def file found at run-time, then ALL variables will be written in diagfi.nc, which will rapidly become huge. You have been warned. Note however that it is a convenient way to have access to the names of all available variables that may be outputted in diagfi.nc.
- The rate at which the outputs are made in diagfi.nc is set by the diagfi_output_rate parameter which is usually set in the callphys.def file and expressed in terms of physical time steps for the Generic PCM. For the Mars PCM, a different flag sets the diagfi.nc output rate using outputs_per_sol.
