description: The topic of the final qualifying work: "Application of submodeling techniques in finite element calculations". This paper is devoted to the topic of using submodeling in the Ansys Workbench 2022R1 program. It considers two variants of submodeling based on data transfer, displacements or forces, from a global model to a submodel. The tasks that were solved during the analysis of various examples consisted, firstly, in considering the specifics of using this technique. Secondly, in the search for differences between displacement-based and force-based submodeling and in fixing the positive and negative sides of each of the method options for solid-state and shell models. Thirdly, for some examples, the influence of the size of the finite element in the global model on the result obtained in the submodel was considered. Fourth, it was tested how the submodeling technique works not only for the elastic behavior of the material, but also for plastic. Fifth, the dependence of the relative errors according to the results on the difference in the deformation energy between the models is obtained. Hypotheses are made about how, knowing the values of the strain energy, to check how close the result obtained is to the exact one.
