Opis:: The objective of the paper was to describethe concept of a virtual, digital equivalent to a physical process. The basic idea of the virtual counterpart for the process called a digital twin is described first. Following this the hybrid computer system dedicated to the design of the optimal manufacturing technology for thin steel strips is presented. The models used in the system and the database are described. Numerical tests showing capabilities of the system recapitulate the work.

VirtRoll computer system
Opis:: The objective of this work was development of the computer system VirtRoll, which allows designing of the arbitrary rolling line and performing numerical simulations using high efficiency hardware architectures. Selection of the mechanical, thermal, microstructural and phase transformation models, which allow decreasing the computing costs while the accuracy of simulations is maintained on the reasonable level, was one of the objectives of the paper. Thus, metamodel was applied in the mechanical part and a simple finite element approach was used in the thermal part of the hot rolling model. Simulations of microstructure evolution in hot rolling and phase transformations during the laminar cooling were based on modified Avrami equation. The system was designed in the client-server architecture, in which client part is in the form of the graphical interface. This interface allows to design of rolling line. The server part is composed of: i) controllers which prepare computing tasks, ii) middleware layer responsible for launching and monitoring of the computing tasks, iii) the layer of numerical computations. Deal.II library dedicated to solve partial differential equations was used for the time step adaptations. All these parts led to short computing times and additionally allowed parallel solution of the optimization tasks. Simulations of thermal-mechanical-microstructural phenomena were performed for the rolling-cooling sequence and the results allowed validation of the system.
