Abstract
The calculation scheme of creation of approximate solutions of the stationary two-dimensional equation of heat conductivity without internal sources of heat by variation methods for an elliptic pipe of constant thickness is offered. At creation of the equation of heat conductivity in a wall of the elliptic cylinder the curvilinear system of coordinates of a special type considering geometry of section is used. As an example, two examples of the solution of a border task are reviewed under boundary conditions of the first sort in the form of the set functions and in the form of constant values of temperature.
