◆ residual_lateral()

void pism::stressbalance::Blatter::residual_lateral ( const fem::Q1Element3 element,

Computes the residual contribution of lateral boundary conditions.

This takes care of "calving front" stress boundary conditions.

FIXME: make p_ocean an input from a parameterization of the melange back pressure.

Reimplemented in pism::stressbalance::BlatterTestvanderVeen, and pism::stressbalance::BlatterTestHalfar.
