Development of information and computing technologies for modelling of pipeline and hydraulic systems

The paper is devoted to the development of information and computational technologies for creating digital twins of real pipeline systems of various types and purposes. The main results of work in the direction of creating the information computing environment “ANGARA”, as a basic technology for setting up and using the information and computing environment, describe its information, computing and analytical functions is presented. The technology of information and mathematical models integration for the creation of information computing systems for pipeline systems calculating of different types is presented. The concept of enterprise unified digital space developing, as well as technologies for remote access to it, is described. The article presents an object-oriented technology of computer modelling of pipeline systems and an example of its application when creating an online application for hydraulic calculations. The technology used by the authors for testing and comparing the effectiveness of various mathematical methods for calculating the flow distribution is presented. Prospective directions of calculation technologies development related to the use of parallel computing technology are presented
