Compatibility of FlowVision 3.13 with Red OS

On May 5, 2022, Russian software manufacturers RED SOFTWARE and TESIS announced the compatibility of the operating system RED OS and the integrated solution for interdisciplinary modeling FlowVision 3.13. Testing was carried out in order to implement an import substitution program for information technologies at critical information infrastructure facilities.

FlowVision is used by engineers in shipbuilding, nuclear power, aircraft and astronautics. This is a Russian comprehensive solution for designers, engineers and technologists to simulate three-dimensional fluid and gas currents, heat transfer, combustion and chemical reactions. FlowVision allows you to solve interdisciplinary problems and effectively use the computing resources of workstations and supercomputers. FlowVision is registered in the Unified Register of Russian Programs for Computers and Databases (No. 2504).

At the beginning of May 2022, employees of federal and regional executive bodies of more than 50 regions of the country work on RED OS. The operating system is actively used by state corporations, including at KII facilities. Its popularity is due to high security standards, ease of use, as well as a developed ecosystem that provides an environment for solving a variety of problems. FlowVision is another import-independent tool available in RED OS, which will allow KII engineers to freely and efficiently perform their work, commented Rustam Rustamov, Deputy General Director of RED SOFT.

In the FlowVision 3.13 release, we completely rewrote the pre-post-processor so that all modules work natively on Linux without using third-party software such as Wine. Since FlowVision is often used at KII facilities for design and virtual development of products, we need to make sure that it is compatible with popular domestic operating systems. We conducted one of the first tests together with RED SOFT specialists and confirmed the compatibility of the updated version of FlowVision 3.13 with RED OS. Now Russian engineers have access to a completely domestic modeling and engineering calculation environment, said Sergey Kursakov, Director General of TESIS.

2016: Flowvision ported to "Elbrus"

On June 10, 2016, Tesis announced the completion of porting the Flowvision engineering calculation system to Elbrus processors^[1].

The porting was carried out by the creator company Flowvision - "Tesis," with the participation of "MCST," the developer of microprocessors "Elbrus," and one of the developers of computer complexes based on them - the Institute of Electronic Controlled Machines named after I. S. Brook (INEUM, part of the "United Instrument-Making Corporation").

Server "Elbrus," (2015)

Flowvision provides a wide range of tasks in the field of hydraulic and gas dynamics and combustion processes. The system is used at enterprises of the military-industrial complex, the rocket and space industry, the aviation and shipbuilding industries, at enterprises Rosatom"."

Flowvision has a client-server architecture. On the client machine, the user sets tasks, then they are calculated on the server, the result is returned back. The client machine is the Elbrus-401 personal computer, and the Elbrus-4.4 computer complex is the server.

There were no fundamental difficulties and problems when creating a version of Flowvision for the Elbrus platform, and all technical issues were resolved with the support of MCST programmers. Vladimir Shmelev, "Tesis" representative of

Porting will help customers perform strategic engineering calculations on a domestic software and hardware platform. The cost of the client-server solution is from 1 million rubles.

FlowVision is based on the numerical solution of three-dimensional stationary and unsteady equations of fluid and gas dynamics, which include the laws of conservation of mass, momentum (Navier-Stokes equations), the equation of state. To calculate complex fluid and gas movements accompanied by additional physical phenomena, such as turbulence, combustion, contact interfaces, porosity of the medium, heat transfer, and so on, additional equations describing these phenomena are included in the mathematical model.

As of April 10, 2015, FlowVision uses a finite-volume approach to approximate the equations of a mathematical model. The Navier-Stokes equations are solved by splitting by physical processes (MAC projection method). FlowVision is based on computational fluid dynamics and computer graphics technologies:

• rectangular design grid with local grinding of design cells
• approximation of curvilinear boundaries of the computed area by subnet resolution of geometry
• import geometry from CAD systems and finite element systems through a surface mesh
• the kernel of the program is written in C++
• has a client-server architecture
• user interface - for MS Windows and Linux operating systems
• analysis system uses high-quality graphics based on OpenGL

FlowVision is built on the platform of a single integrated environment, in which the preprocessor, solver and post-processor are combined and operate simultaneously.

The function of the preprocessor includes importing simulation region geometry from geometric modeling systems, setting the environment model, arranging initial and boundary conditions, generating or importing a simulation mesh, and setting convergence criteria.

Control is then passed to the Solver, who starts the account process. When the required convergence criterion is reached, the account process can be stopped.

The results of the calculation directly during the invoice are available for the Postprocessor, which processes the data - visualizing the results and saving them to external data formats.

Such a scheme allows you to conduct modeling and at the same time, visualizing the value of any gas-dynamic variable, analyze the calculation results, change the boundary conditions and parameters of the mathematical model. The architecture of the FlowVision software complex is modular, which allows you to add new functionality and make improvements.

In 2001, by the decision of the Main Council of the Ministry of the Russian Federation , FlowVision was recommended for inclusion in the program of teaching fluid and gas mechanics in universities. Russia

In 2005, FlowVision was tested and received a certificate of conformity from the State Standard of Russia.
