Abstract. This paper analyzes the key challenges encountered during large-scale calculations using simulation-based computer models in research, development, testing, and engineering projects and proposes solutions based on a systematic approach. The features of creating digital computer models structured as hierarchical systems of functional digital twins and fractals are examined in detail. The study also specifies the technology for organizing and conducting simulation modeling, employing original tools for automating the preparation of input data, parallelizing computations, and analyzing results.

Keywords: computer model, simulation modeling, digital twin, digital fractal, parallelizing computation
