This section explains the geometry and stress balance 11 mechanisms in PISM that apply to floating ice, at the vertical calving faces of floating 12 ice, or at marine grounding lines. The physics at calving fronts is very different from 13 elsewhere on an ice sheet, because the flow is nothing like the lubrication flow addressed 14 by the SIA, and nor is the physics like the sliding flow in the interior of an ice domain. 15 The needed physics at the calving front can be thought of as boundary condition 16 modifications to the mass continuity equation and to the SSA stress balance equation. The 17 physics of grounding lines are substantially handled by recovering sub-grid information 18 through interpolation. 19 20 .. toctree:: 21 22 pik.rst 23 24 mask.rst 25 26 calving.rst 27 28 melange.rst
