add_contribution() void pism::fem::Element::add_contribution ( const double *  K, Mat  J  ) const protected Add Jacobian contributions. Add the contributions of an element-local Jacobian to the global Jacobian matrix. The element-local Jacobian should be given as a row-major array of Nk*Nk values in the scalar case or (2Nk)*(2Nk) values in the vector valued case. Note that MatSetValuesBlockedStencil ignores negative indexes, so values in K corresponding to locations marked using mark_row_invalid() and mark_col_invalid() are ignored. (Just as they should be.)
