Practical usage

Running PISM requires many practical decisions, from pre-processing input data and selecting diagnostic quantities to save to monitoring running simulations and managing code modifications; see the following sub-sections for details.

• Handling NetCDF files
• Input and output
  • PISM’s I/O performance
• Understanding adaptive time-stepping
  • Parameters
• Scalar diagnostic quantities
  • Parameters
  • Comments
• Spatially-varying diagnostic quantities
  • Parameters
• Snapshots of the model state
  • Parameters
• Run-time diagnostic viewers
• PISM’s configuration parameters and how to change them
  • Managing parameter studies
  • Saving PISM’s configuration for post-processing
• Regridding
• Signals, to control a running PISM model
• Balancing the books
  • 2D diagnostics
  • Scalar diagnostics
  • Mass accounting in subglacial hydrology models
  • Mass accounting in the PDD model
