Here are just some of the requested changes in the program:

  • Captions (legends) for palettes
  • The boundary condition, which allows you to set a fixed profile of velocities
  • Controls for customized displaying plots in the monitor window
  • The status tab now contains additional fields: number of cells of the boundary layer grid, values of convective and surface of the time step, etc.
  • Now you don’t have to install MPI if use of FlowVision is assumed to be used only on one processor.
  • Now it is possible to visualize streamline on surfaces.
  • You have to do much less mouse clicks when working with Terminal.
  • New variables have been added, Reference Pressure and Reference Temperature.
  • A new layer, Computational grid section, now can be displayed by the Viewer module.

During the fair; Akana stand (#1408) has been open to visitors in Hall 14. An international community of design and simulation engineers from various defence companies have visited the stand for gaining insights about unique capabilities of FlowVision CFD software and its applications, mainly in the defence industry.

The “Elbrus” logistics support ship, build at the shipyard ‘Severnaya Verf’, has been launched to sea on May 15, 2017. FlowVision CFD software has been used as a virtual hydro channel and wind tunnel for evaluation and optimization of hull form design.

Engineering design and simulation specialists from companies Digital Marine and JSC Spetssudoproekt conducted CFD simulations of Elbrus including hydrodynamics and aerodynamics effects on ship hull, also examining the operating conditions of helicopter on the ship deck (analogous to wind tunnel tests).

The CFD software package FlowVision was used for the most complicated calculations of oil distribution in the crankcase of the leading axle of the KAMAZ truck. This pilot project was successfully completed in close cooperation between the specialists of TESIS and KAMAZ.

Geometrical model of a fragment of a crankcase of the driving axle

Based on the three-dimensional CAD-model of the crankcase created by the designers of KAMAZ company, the specialists of TESIS have developed a mathematical model which describe the flow of oil partially filling the crankcase volume under the action of rotating structural parts and gravity field. The calculations have been performed together for various modes of operation of the simulated unit differing in the operating temperature of the transmission oil and the angular velocities of the rotating parts, the driving and central wheels, and also the satellites.

The oil distribution in the crankcase volume

The analysis of modeling results carried out by specialists of KAMAZ and TESIS made it possible to trace the dynamics of movement and distribution of oil in the crankcase volume, as well as to evaluate the effectiveness of lubricating the surfaces of structural parts.

Based on expert analysis of the results of calculations, conclusions were drawn about the adequacy of the calculated design model and the possibility of using the FlowVision software package to solve the issues and design basis for the lubrication of complex mechanical systems for KAMAZ vehicles. The developed approach gives the designer the opportunity at all stages of design to obtain and analyze reliable and comprehensive information on the characteristics of the lubrication system.

Successful solution of the task was made possible thanks to the creative approach and well-coordinated work of the pilot project team - specialists of KAMAZ and TESIS, as well as a number of innovative technologies and unique functionality of the software package FlowVision, which include:

  • Direct import of the geometry of modeled object from the CAD-system using a wide list of supported formats;
  • Automatic generation of a computational grid with local dynamic adaptation, which makes it possible to obtain an exact solution with minimal costs for preparing the task for calculation and for the required computing resources;
  • Simulation of the complex motion of a system of solids in liquid according to a given law or under the action of hydrodynamic forces;
  • Simulation of flows in the gaps without the construction of a detailed mesh inside the gap - calculation of the flow of oil in the channels formed by the gears of the rotating wheels, satellites and bearings;
  • Extensive opportunities for the presentation and analysis of modeling results:
    • A realistic representation of the distribution of oil in the volume of the constructions;
    • Visualization of surfaces for lubricated parts;
    • Non-stationary circulation of oil in the lubrication system;
    • Distribution of pressure on the walls of the constructions;
    • Field of velocities in the calculated domain.

Based on the results of the pilot project, KAMAZ company and TESIS company agreed on further long-term cooperation with the aim of evolution a computational model and creating new modern methods for modeling physical processes based on FlowVision and ABAQUS software packages for use in the design of various KAMAZ vehicles.

The 15th International Forum «Engineering Systems», organized by TESIS company, was held on April 11-12, 2017 in the Moscow City business center. The Forum included three conferences:

  • Computational fluid dynamics (CFD):  FlowVision users’ meeting
  • Finite element analysis (FEA): SIMULIA Abaqus Users’ meeting
  • Conference «Modeling of metal forming and heat treatment processes in DEFORM and JMatPro»

Capvidia participated in the Biomedical Engineering Symposium & Workshop 2016 held in 6th December 2016, Munich, Germany organized by Dassault Systemes Deutschland GmbH.

This special one-day event provided an insight about the SIMULIA Abaqus Living Heart Human Model (LHHM) state of development and how this Model leads to better treatments and medical products. The attendees had the chance to learn about the simulation process from a 2D scan to a beating heart model. In this scope; the unique work “Fluid-Structure Interaction in a Beating Human Heart Model” performed by the cooperation of Capvidia and Dassault Systemes Simulia was presented by Wojtek Zietak, Product Manager at Capvidia.

The presented work is in the scope of the Living Heart Project, leaded by Dassault Systemes SIMULIA and conducted by various cardio-vascular research institutions, clinicians and tool designers accompanied with leading engineering software vendors. Capvidia is the CFD simulation partner of the Living Heart Project aiming to integrate FlowVision and Abaqus for a realistic simulation of blood flow in a beating human heart taking into consideration the fluid-structure interaction between blood, heart tissues, mechanical/tissue valves and time-dependent boundary conditions as a function of human body resistances. Resultantly, a patient-specific tool and methodology for optimization of heart device design are targeted.

The key issues and simulation challenges that have already been realized and presented during the Biomedical Engineering Symposium & Workshop 2016 are:

  • Extraction of blood volume from the SIMULIA Abaqus Living Heart Human Model
  • FSI calculations of beating heart with natural conditions
  • FSI calculations of beating heart with moving artificial mechanical valves

Capvidia participated in the NAFEMS European Conference; Multiphysics Simulation 2016 held in 15-16 November 2016, Copenhagen, Denmark.

In the scope of medical sessions; a novel work “Fluid-Structure Interaction in a Beating Human Heart Model” performed by the cooperation of Capvidia and Dassault Systemes Simulia was presented.
