Abstract: Introduction. The widespread use of cast products made of aluminum and its alloys requires ensuring a high -quality structure of the castings, on which their operational properties depend. Controlling the process of forming a high-quality structure of castings is possible, in particular, by the method of electrocurrent treatment of melts. Problem Statement. The melt medium being inaccessible for direct measurement of the processing parameters, the only way to realize the control of treatment conditions is numerical simulation of these parameters. However, the complexity and interdependence of multiphysics processes of melt electrocurrent treatment have led to an unconventional approach to the formulation of their mathematical models and computational procedures. These circumstances have determined the features of the tasks for the construction of appropriate computer models and their application. Purpose. The development of a new pattern-modular system for computer modeling of multiphysics processes of electric current treatment of melts to control the conditions of the formation of a qualitative structure of castings. Materials and Methods. The material of the research is a set of model problems of multiphysical processes of electrocurrent treatment and their ontology, the integral equations and their properties, as well as databases on the parameters of simulated objects, which describe these processes. The method of ontological taxonomy has been used to create a taxonomic codifier, with the help of which model problems and mathematical tools for their solution have been systematized. Based on the signs of similarity, the method of formalization of integral equations of coupled multiphysics processes has been applied. Results. The unified patterns of basic algorithmic procedures and a library of program modules for computing operations of partial tasks, for which a unique code is assigned according to the codifier have been developed. Combining the patterns with different modules that are identified by the indicated codes has made it possible to form a wide range of computer models reflecting multiphysics processes. A flexible system for computer modeling of multiphysical processes has been built and its efficiency for simulating the modes of electrocurrent treatment of melts has been confirmed. Conclusions. The results obtained have enabled controlling the conditions of electrocurrent treatment of melts to form a high -quality structure of cast metal.
