[mpas-developers] adding user-friendliness to MPAS trunk

[Michael Duda]

Hi, All.

I'd like to add a small bit of code in
src/framework/module_io_input.F that will inform the user when the
input grid file (either input or restart) is missing. Without this
change, the errors generated by the code when a grid.nc or
restart.nc file isn't present don't give any specific indication
of what caused the crash. At least in my case, it's sometimes
taken me a minute or two to realize that it's not a problem with
the code, but just a missing input file that caused a run to fail.

The change is simply to add this bit of code

below the call to nf_open(...) in module_io_input.F.

If anyone has any suggestions for improvement or objections,
please let me know.

Cheers,
