Detailed Description
Implements the shallow ice approximation stress balance.
- ice geometry (thickness, bed elevation, surface elevation, cell type mask)
- ice enthalpy
- ice age (could be used to compute the grain size)
- sliding velocity
Outputs:
- horizontal velocity (3D fields)
- diffusive ice flux (for use in the geometry update)
- maximum diffusivity (used to determine the maximum allowed time step length)
- volumetric strain heating
