At UQAM GenPhysX is currently only working on alea.

To get access to GenPhysX (which uses SPI) you need to load:

      module load utils/SPI

As input GenPhysX needs to know the model grid in form of the tictacs of the full model grid. On our UQAM servers you can create them from your gem_settings.nml with the command:

     ~winger/ovbin/k.grille

The file you need as input for GenPhysX is called "tape1_model".

For the different available datasets check here.

When using USGS set:

    TOPO=USGS
    VEGE=USGS_R
    MASK=USGS_R
    SOIL=JPL

When using CCI-LC set:

    TOPO=GMTED75  # missing Antarctica and Greenland!!!
or
    TOPO=GMTED30  # lower resolution

    VEGE=CCI_LC
    MASK=CCI_LC
    SOIL=BNU

Example script to create geophysical fields:


#!/bin/bash

#  Set the following parameters
exp=domain_name    # Domain name (name of geophys files)
cd /Path/of/Geophys/directory/Geophys_${exp}   # Destination directory containing already the file 'tape1.model'!!!
                                           #   -> must NOT be in the home!!!
email="your.email@address"                # Email address to which a confirmation email will get send after completion

# Set following parameters to dataset of your choice, following above examples:
TOPO=...
VEGE=...
MASK=...
SOIL=...
