Using Rounding Function in the Problems of Finite-Element Analysis

V. S. Kosachev, E. P. Koshevoy, S. A. Podgornyy

Abstract


This work offers to supplement polynomial elements used by the step function of Heaviside and rounding functions which allows to simplify and formalise the record of test piecewise continuous function applying it for continual problems solution by the method of Galerkin.

Key words: Finite element method; Galerkin; Rounding function
