The possibility of constructing a system of specialized solutions for strength analysis based on CAE Fidesys is considered. The results of testing CAE Fidesys are presented. The finite element method and the spectral element method implemented in CAE Fidesys are discussed for the problems of mechanics of a deformable solid. The opinion is expressed that at this stage of the development of CAE Fidesys it can be used as an alternative CAE for carrying out control calculations, especially when solving non-typical tasks, in the solution of which there is a need to modify and adjust the main computational algorithms incorporated in the software. As a part of CAE Fidesys all the necessary elements are provided to ensure the effectiveness of its application - a preprocessor that provides the generation of finite element models, a modular processor for solving linear and nonlinear static and dynamic problems, buckling problems, estimation effective properties of composite materials, contact problems, postprocessor for visualization and processing of results. The results of testing CAE Fidesys are presented in comparison with the results obtained in ANSYS. The main purpose of the testing was to evaluate the possibilities of CAE Fidesys in terms of: importing geometry from CAD systems; the effectiveness of finite element mesh generator; determination of the stress-strain state of assemblies with a variable contact zone; solving dynamic problems, including modal and harmonic analysis. Testing of CAE Fidesys was performed on test cases representing the problems which are frequently faced in practical work. It is noted that the distinctive feature of CAE FidesСѓs is the high-order spectral elements allowing one, in some cases, increase the accuracy of calculation without rebuilding the finite element mesh. It is noted that a comparative analysis of the calculations done on the models with similar finite element meshes conducted in CAE FidesСѓs and ANSYS shows good coincidence of the results. The conclusion is that CAE FidesСѓs can be used for solving different problems of structural analysis in addition to another CAE software available on the enterprise, and also taking into account the practical needs of active users, it can be considered, when combined with the user's requirements, as the basis of an industrial solution for a structural analysis.
Keywords: software complex, strength engineering analysis, test results, modification and tuning of computational algorithms.
