ISSM Create Domain Instructions

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
