First go to the FES2012 directory:

cd ~/monday/FES2012

Define GENESIS environment variable:

export GENESIS=~/softs/xscan

Then edit FES2012.startup:

kate FES2012.startup&

Invoking xscan:

$GENESIS/bin/xscan -s <<startup filename>>


$GENESIS/bin/xscan -s FES2012.startup

Standard visualisation under xscan (sirocco-genesis)

  1. Startup files
  2. bathymetry: plotting and editing
  3. shorelines
  4. model outputs
    1. 2D (layers) display
    2. 3D (sections and profiles) display
  5. controlling plot paramaters and printing
  6. GIS: using geo-referenced images


Unstructured mesh generation and editing

  1. exercise I : automatic mesh generation with ztugo
  2. mesh refinement
    1. doubling resolution
    2. more subtle refinement
  3. element edition
    1. vertices edition
    2. connection edition
  4. boundary code construction
  5. plotting unstructured fields
  6. Examples of Unstructured files:

    To see some example of files that xscan can read:

    cd /home/sirocco/monday/xscan_files/


    The different type of files:

ASCII format

    - *.s2r are ASCII files containing real scalar data (i.e. elevation).

    - *.v2r are ASCII files containing real vector data (i.e. mean velocity field).

    - *.s2c are ASCII files containing complex scalar data.

    - *.v2c are ASCII files containing complex vector data (i.e. tidal currents, ellipse)

NetCDF format

    - * are classic structured netcdf files.

    - *.nc without the SG prefix are unstructured netcdf files.

    - * are 3D unstructured netcdf files.
