weight() static int pism::stressbalance::weight ( bool  margin_bc, int  M_ij, int  M_n, double  h_ij, double  h_n, int  N_ij, int  N_n  ) static Compute the weight used to determine if the difference between locations i,j and n (neighbor) should be used in the computation of the surface gradient in SSA::compute_driving_stress(). We avoid differencing across ice margins if stress boundary condition at ice margins (CFBC) is active grounding lines ice margins next to ice free locations above the surface elevation of the ice (fjord walls, nunataks, headwalls) Definition at line 83 of file SSAFDBase.cc.
