Whenever you have problems with a simulation, let me know what the problem seems to be and where I can find your config files!

These are the needed config files:toc

If you want to start a new simulation I suggest you copy a set of config files from another simulation, which is as close as possible to the one you want to run .

configexp.cfg

This file is a shell parameter file which gets sourced by the scripts. You can put comments in it like in any other shell script and there must never be a space before or after the '=' sign. The parameters set here determine:

• name of experiment (always keep *_YYYYMM and the end of the name)
• start and end date
• model time step
• model levels
• number of cores to run on
• where to find the input files
• where to archive the output
• control output of pilot files
• ...

When running UQAM style there are several more parameters to be set than in ECCC's forecast mode. These extra parameters all start with 'CLIMAT_...'.

General GEM parameters:

...

Keep in mind that the minimum number of grid points for a GEM tile is ~25:
   pilot region (Grd_maxcfl+7)  + blending (Lam_blend_H (default 10))  + 5 points
If you change the tiling and your simulation suddenly crashes right at the beginning of the model executable it might be that the tiling you chose does not work for this grid. Choose another tiling and try again.
In general you want to keep your tiles as square as possible to keep the amount of data exchange between tiles to a minimum.

Extra parameters when running "UQAM style":

gem_settings.nml  

outcfg.out

and then modify them.
