| Abstract: | An existing algorithm of automatically forming of cover system in the numerical manifold is introduced in this paper.Some improvements are presented to make the algorithm more universal and capable of complex boundary conditions. The improved algorithm proved to be effective for both continuum and discontinuity of any boundary condition in several numerical examples. |
