摘要：
We propose a construction of a trivariate C1 macro-element over a special tetrahedral partition and compare our construction with known C1 macro-elements which are summarized in this paper. Also, we propose an improvement of the Alfeld construction of a C1 quintic macro-element such that the new scheme is able to reproduce all polynomials of total degree ≤5.
