    The Triangular Hermite Finite Element Complementing the Bogner-Fox-Schmit Rectangle
[Text] : статья / L. Gileva, V. Shaydurov, B. Dobronets // Applied Mathematics. - 2013. - Vol. 4. - p. 50-56DOI 10.4236/am.2013.412A006 . -

Аннотация: The Bogner-Fox-Schmit rectangular element is one of the simplest elements that provide continuous differentiability of an approximate solution in the framework of the finite element method. However, it can be applied only on a simple domain composed of rectangles or parallelograms whose sides are parallel to two different straight lines. We propose a new triangular Hermite element with 13 degrees of freedom. It is used in combination with the Bogner-Fox-Schmit element near the boundary of an arbitrary polygonal domain and provides continuous differentiability of an approximate solution in the whole domain up to the boundary.

Аннотация: The Bogner-Fox-Schmit rectangular element is one of the simplest elements that provide continuous differentiability of an approximate solution in the framework of the finite element method. However, it can be applied only on a simple domain composed of rectangles whose sides are parallel to two different straight lines. We propose a new family of triangular Hermite elements that involves straight-sided elements and elements with a curved side. Such an element can be used in combination with the Bogner-Fox-Schmit element near the boundary of an arbitrary polygonal domain or a domain with a curved part of the boundary and provides continuous differentiability of an approximate solution in the whole domain up to the boundary.

    Hermitian finite element complementing the Bogner–Fox–Schmit rectangle near curvilinear boundary
/ B. Dobronets, V. Shaydurov // Lobachevskii J. Math. - 2016. - Vol. 37, Is. 5. - P527-533, DOI 10.1134/S1995080216050036 . - ISSN 1995-0802
Аннотация: We discuss the Hermitian finite elements of high-order accuracy for solving boundary value problems for partial differential equations in domains with curvilinear boundaries. New elements are constructed in such a way that they can be used in conjunction with the Bogner–Fox–Schmit rectangular elements. © 2016, Pleiades Publishing, Ltd.

    New Hermite finite elements on rectangles
/ L. Gileva, E. Karepova, V. Shaydurov // AIP Conference Proceedings. - 2016. - Vol. 1773: 8th International Conference for Promoting the Application of Mathematics in Technical and Natural Sciences, AMiTaNS 2016 (22 June 2016 through 27 June 2016, ) Conference code: 124420, DOI 10.1063/1.4964999 . -

Аннотация: In the paper, we propose new biquadratic and bicubic Hermite elements on a rectangle. These elements involve the values of a function and its second-order derivatives as degrees of freedom. The proposed elements are more efficient than Lagrange elements of the same degree. Numerical results confirm the theoretical estimates of convergence. © 2016 Author(s).

[Текст] : научное издание / Л. В. Гилева, Е. Д. Карепова, В. В. Шайдуров // Решетневские чтения. - 2016. - Т. 2, № 20. - С. 126-127 . - ISSN 1990-7702

УДК

Аннотация: Предложен новый бикубический эрмитов элемент на прямоугольнике и дополняющие его треугольные эрмитовы элементы, в том числе на треугольнике с криволинейной стороной. Совместное использование прямоугольных и треугольных элементов позволяет применять их для решения задач в многоугольных облостях и областях с криволинейными участками границы.
In the paper, a new bicubic Hermite element on a rectangle and related Hermite elements on a straight-sided triangle and on a triangle with a curved side are proposed. The combination of these elements enables one to apply them for problems in a polygonal domain and in a domain with curved parts of the boundary.
