A Cr trivariate macro-element based on the Alfeld split of tetrahedra
نویسندگان
چکیده
We construct trivariate macro-elements of class Cr for any r ≥ 1 over the Alfeld refinement of any tetrahedral partition in R3. In our construction, the degree of polynomials used for these macro-elements is the lowest possible. We also give the dimension formula for the subspace of consisting of these macroelements.

A New Kind of Trivariate C 1 Macro - ElementMing
We propose a construction of a trivariate C 1 macro-element over a special tetrahedral partition and compare our construction with known C 1 macro-elements which are summarized in this paper. Also, we propose an improvement of the Alfeld construction of a C 1 quintic macro-element such that the new scheme is able to reproduce all polynomials of total degree 5. x1. Introduction The study of triv...
متن کاملTwo condensed macro-elements with full approximation power
A variant of the classical C Powell-Sabin-12 macro-element is defined that has the same approximation power, but has fewer degrees of freedom and only requires vertex data. The same idea is then applied to a related C trivariate macro-element. §
متن کاملA C Quadratic Trivariate Macro-element Space Defined Over Arbitrary Tetrahedral Partitions
In 1988, Worsey and Piper constructed a trivariate macro-element based on C quadratic splines defined over a split of a tetrahedron into 24 subtetrahedra. However, this local element can only be used to construct a corresponding macro-element spline space over tetrahedral partitions that satisfy some very restrictive geometric constraints. We show that by further refining their split, it is pos...

متن کاملTrivariate C Polynomial Macro-Elements
Trivariate C macro-elements defined in terms of polynomials of degree 8r + 1 on tetrahedra are analyzed. For r = 1, 2, these spaces reduce to well-known macro-element spaces used in data fitting and in the finite-element method. We determine the dimension of these spaces, and describe stable local minimal determining sets and nodal minimal determining sets. We also show that the spaces approxim...
