ABSTRAKT

The paper deals with the scheme of the finite element method with the choice of basic functions for elliptic boundary value problem. The main feature of this scheme is that the basic functions forming an approximate solution are not fixed in advance but should be calculated along with the values of node parameters. Computational experiment demonstrated that the scheme had a much higher accuracy compared with conventional schemes for which the basic functions are fixed.
