The key problem in the use of previously proposed boundary conditions identification method is the solution of intermediate boundary-value problems. These are quite complex boundary-value problems of structural elements conjugation of branched thin-walled spatial systems, such as bearing surfaces and hulls of aircraft structure. In solving the boundary conditions identifying problem for selected block-element the industrial finite element method can substantially help. On the other hand, boundary conditions identification method as such can help the finite element method to choose the effective type of finite element typical for the considered class of solid mechanics problems. This idea “boundary conditions identification method ↔ finite element method” is the basis of the study. The fruitfulness of combining two essentially different methods is shown by carrying out numerous calculations on a particular example of a rather simple but not trivial problem.
