Strength analysis problems are those engineering tasks that aim to calculate strength properties of structures. The modelling in this sphere is of such complexity that it is often difficult to integrate a geometric model (CAD) and the analysis of physical impact exerted on it (FEM). This paper describes a prototype of an open-source system that integrates CAD and FEM. The strength analysis task is used to illustrate the integration. The system is deployed by means of the Docker platform and uses Jupyter Notebook for strength analysis.
