Hi Jean;
Nothing is changed other than the netCDF options. I have also tried running
without netCDF enabled, but the same problem occurred.
It's still stuck. Here I attached those three files again, plus the
"Coupler.0000.clog" file from "rank_0" directory.
The program is still running (consuming CPUs) but these files are not
getting updated anymore, nor do other files.
Even I can send the whole directory if you wish!
