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 your tutorial folder of choice: Users/geodynamics/Documents/ISSM/trunk/examples/AntByrd

Step 2: Open Start.m file

  • Open the Start.m file within the tutorial folder
  • Edit the file so steps = [0 1]
    • Step 0 will designate all data files for the model run
    • Step 1 will run CreSIS.m file which designates variable to the higher resolution data(usually from CreSIS)
  • Run the file
    • A contour map of the study area should be displayed

Step 3: Assign model domain

  • In the command window type: exptool(‘test.exp’)
    • An interactive gui should pop up on the left hand side of the screen
  • Click the button that reads “add a contour (closed)
  • Trace an outline of the domain you would like for your model, you can use as many points as you like
  • Press “Enter” and then quit the gui
    • Matlab should save your “test.exp” file inside the tutorial folder
  • Rename “test.exp” to “Outline.exp”

Step 4: Create Mesh

  • Open meshSetup.m
  • Edit the file so setupSteps = [1 2 3]
  • Several plots should appear including:
    • Original mesh
    • Velocity-refined mesh
    • High resolution bed elevation
    • Low resolution bed elevation
    • Difference between high-res and low-res bed elevation

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
