  1. - New: The function DoFTools::make_zero_boundary_constraints() applies - zero boundary constraints to a (symmetric preserved) matrix without - accessing the sparsity pattern. Use cases are for when the sparsity pattern - of the matrix is unknown / inaccessible. + New: The function DoFTools::make_zero_boundary_constraints() computes the + constraints that result from requiring the degrees of freedom at the + boundary to be zero. This allos to apply zero boundary constraints to + a matrix in the same way as other constraints, rather than going + through the MatrixTools::apply_boundary_values function.
