The Numerical Solution of the Bitsadze-Samarskii Nonlocal Boundary Value Problems with the Dirichlet-Neumann Condition

الملخص EN

We are interested in studying the stable difference schemes for the numerical solution of the nonlocal boundary value problem with the Dirichlet-Neumann condition for the multidimensional elliptic equation.

The first and second orders of accuracy difference schemes are presented.

A procedure of modified Gauss elimination method is used for solving these difference schemes for the two-dimensional elliptic differential equation.

The method is illustrated by numerical examples.
