Applied Physics and Mathematics Annotation << Back ABOUT ONE METHOD OF SOLUTION OF BOUNDARY VALUE PROBLEMS WITH ELLIPTIC OPERATORS V.I. RYAZHSKIH, A.V. RYAZHSKIH, V.A. RYABTSEV Discusses the solution of the boundary problem of temperature fi eld of thin fl at isotropic plate in the variational formulation. The border area of the task defi nition is covered with the ultimate elements and the inside fl at uniform grid. The problems of forming functional of the energy objectives and determine its minimum. An example of a solution to this problem, and the comparative evaluation of the accuracy of the solution. Keywords: fl at area, boundary value problems of heat conduction, fi nite elements, fi nite difference, optimization. Contacts: E-mail: ryazhskihav@bk.ru Pp. 46-50.
