Dennis Abts,John Kimgher order mixed-order TVFEs. This paper provides a description of certain mixed-order TVFEs for triangular elements and presents numerical results demonstrating the merits of hierarchical mixed-order TVFEs. It is hoped that the paper will provide insight in the nature of hierarchical mixed-order TVFEs and serve as a rationale for their use.
