Digital Twins for the Porous Structures of Aerogels with the Use of the Cellular Automation Approach and Bezier Curves.

In this paper, a cellular automation model developed on the basis of Bezier curves with the use of a cellular automation approach for the creation of digital twins for porous nanostructures of different nature is proposed. Some numerical experiments on the creation of digital twins for the synthesized experimental samples of chitosan-based aerogels are carried out. The structural characteristics of the digital copies and experimental samples are compared, allowing us to conclude that the model is correct. The resulting digital twins can be used for predicting the properties of porous fiber materials, in particular, chitosan-based aerogels, to provide the partial replacement of real experiments by computational ones and, consequently, to decrease the expenditures on the development of new materials with specified properties.
