Jump to: navigation, search

Step 1: Open Matlab

  • In command line type: addpath ~/Documents/ISSM/trunk/bin/ ~Documents/ISSM/trunk/lib/
    • This has to be entered every time you open up Matlab and run ISSM
  • In the open file header navigate to the Ant_Create_Domain folder Users/geodynamics/Documents/ISSM/trunk/examples/Ant_Create_Domain

Step 2: Create Personalized Start file

  • Open the GenericStart.m file within the tutorial folder
  • Edit the file so steps = [0 ]
    • Step 0 will designate all data files for the model run
  • Personalize the runName for your wanted domain name
    • Edit ‘InsertRunName’ to be the wanted domain name (example: ‘Mullock’)
  • Save as personalized start file
    • Example: save as MullockStart.m

Step 3: Create Model Domain

  • Open Outline.exp
  • Personalize Outline.exp for domain coordinates
    • Rename the first line(Example: Name: MullockOutline)
  • Insert X positions and Y positions of Polar Stereographic coordinates
    • Note: X pos is Easting and Y pos is Northing
  • If you need to convert from latitude and longitude, see the Polar Sterographic Conversion instruction page
    • You must have 5 points to have a closed box (1st and 5th coordinates will be the same)
  • Save as personalized outline .exp file
    • Example: save as MullockOutline.exp

Step 4: Create Mesh

  • Open meshSetup.m
  • Edit the file so setupSteps = [1 2]
  • Edit domain to be your personalized outline file
    • Example: domain ‘ [‘./MullockOutline.exp’];
  • Run meshSetup.m
  • Several plots should appear including
    • Unrefined Grid
    • Velocity-Refined Grid
    • Bed elevation (low resolution)

Step 5: Solve

  • Open runme.m
  • Edit file so steps = [2:8]
  • Several more plots should appear including
    • Grounded vs. floating
    • Ice vs. no ice
    • Bed elevation
    • Friction Coefficient
    • Observed velocity
    • Modeled SSA Velocity
    • Modeled HO Velocity
    • HO-Observed Velocity
    • SSA-Observed Velocity
    • HO-SSA Velocity
    • HO Surface- HO base Velocity
    • Observed Surface velocity
    • Modeled HO Surface Velocity
