ANSYS, Inc - a global innovator of simulation software and technologies designed to optimize product development processes announced the winners of 2009 Multiphysics Image Gallery Competition.

For the first time in the 8-year history of ANSYS Image Contests two companies from Russia are in the list of winners - EMT R  (Moscow) and CompMechLab  (St.Petersburg) with projects Aeroelastic simulation of air engine fan (EMT P) and FE analysis of human brain for solving the forward problem in Magnetic Field Tomography (MFT) (CompMechLab and City University London) became winners of the Competition.

For CompMechLab it is the fourth victory in ANSYS Image contests (2003, 2004, 2008 and 2009). This is a unique achievement among 79 winning companies in 2002-2009. 

ANSYS, Inc - a global innovator of simulation software and technologies designed to optimize product development processes announced the winners of 2009 Multiphysics Image Gallery Competition.

Multiphysics Image Gallery Competition was launched in 2008, based on the success of annual ANSYS European Wall Planner competition. Thus year the competition is expanded globally in an online format.

According to the Competition rules, twelve winners are to be exhibited in an all-new Online Multiphysics Gallery on ANSYS.com. This gallery will showcase a collection of the most striking images that illustrate real-world multiphysics applications using ANSYS software from around the globe. Images are judged on the quality of theirs application of multiphysics software from ANSYS and the resulting benefits to the submitting company.

Image contets were launched by ANSYS Inc. in 2002 and are held annualy. Among 69 winners of 2002-2008 contests the world-leading industrial companies are presented: Airbus, Alstom, Ferrari, GE Oil & Gas, German Aerospace Center, Robert Bosch Kft., Siemens Power Generation and many others.

Winners of 8th ANSYS Image Contest - 2009 Multiphysics Image Gallery Competition

	WINNER Europe - Selex Communications (Italy) ANSYS Mechanical & Ansoft HFSS Communications use ANSYS Mechanical for RMS and depointing analysis on Satellite Antenna in Carbon fiber using command for layered structures directly on Workbench. Different conditions are investigated, from wind pressure, to solar radiation. Displacements are used to validate deformations on Ansoft HFSS for functionality.
	WINNER General International Area - MAHLE Metal Leve S.A. (Brazil) ANSYS FLUENT & Gambit Mahle utilised Gambit & ANSYS FLUENT to study thermo-fluid changes in rail and cable tunnels without having to build the expensive test-rig.
	WINNER North America - Camoplast Inc. (Canada) ANSYS Workbench Simulated the elastomer track structure under different load cases. with the powerful built-in hyperelastic material model tools, Camoplast was able to simulate different scenarios to determine the maximum constraint inside layers for design optimisation. Those tools help us to create higher quality products and limit prototype iterations with simulation.
	Runner up - Astec (USA - TN) ANSYS FLUENT & EDEM ANSYS FLUENT coupled to the DEM solver EDEM was used to simulate heat transfer from a natural gas burner to rock particles in an aggregate dryer.  The simulation provides invaluable insight into the drying process enabling the internal features of the drum to be optimized for increased drying efficiency resulting in better performance and lower energy costs.
	Runner up - Institute of Thermal Technology, Silesian University of Technology (Poland) ANSYS FLUENT & ANSYS Coupled fluid flow, heat transfer and electromagnetic processes within naturally air-cooled three-phase electrical transformer station.
	Runner up - EMT-R (Russia) ANSYS CFX, ANSYS FLUENT, ANSYS Mechanical, FSI, TurboGrid Aeroelastic simulation of air engine fan in ANSYS CFX. EMT R used ANSYS CFX and ANSYS Mechanical for aeroelastic simulation of modern air engine fan.
	Runner up - Forschungszentrum Dresden- Rossendorf ANSYS Workbench / ANSYS CFX Lorentz force driven rotational flow around a micro electrode during copper deposition under the influence of an external magnetic field.
	Runner up - Mott Macdonald / Imperial College London (UK) ANSYS CFX and ANSYS Rigid Body Module Simulation of fluid-structure interaction at high wind speeds for a long-span bridge deck. Image displays snapshots of the induced flutter motion of the deck with contours of enstrophy illustrating the production and transport of vorticity.
	Runner up - Institute of Applied Mechanics Brno, Ltd. (Czech Rep.) ANSYS Multiphysics IAM Brno, ltd. used ANSYS Multiphysics to computation of dynamic characteristics and vibrations of the bucket wheel excavator SchRs 1320/4x30. This work is one part of the project FT-TA4/018: "Modern trends of increasing of equipment reliability for open-cast mining of utility minerals."
	Runner up - EPCOS NL (Netherlands) ANSYS Multiphysics Using true multiphysics incorporating fluid, electrostatic and mechanical effects, engineers are simulating the transient dynamic response of an innovative RF-MEMS switch for improving cell phone signal strength.
	Runner up - CompMechLab (Russia) ANSYS & EMAG Used Ansys/EMAG to perform time-dependent FE analysis of human brain for solving the forward problem in Magnetic Field Tomography (MFT) brain imaging based on magnetoencephalography (MEG). Various FE solutions allowed the computation and analysis of tiny magnetic fields (10-100 fT) produced by neural currents in the brain associated with cognitive processing.
	Runner up - CADFem / Elektromotorenwerk (Germany) ANSYS Multiphysics The image shows the magnetic flux density of an electric motor displayed on the rotor geometry as well as an eigenmode for the motor housing.

Two remarkable events happened with announcement of 2009 Competition results. For the first time in the 8-year history of ANSYS Image Contests:

Two companies from Russia are in the list of winners -  EMT R  (Moscow) and CompMechLab  (St.Petersburg) with projects:

Aeroelastic simulation of air engine fan (EMT P)

FE analysis of human brain for solving the forward problem in Magnetic Field Tomography (MFT)

(CompMechLab and City University London)

Summary. This paper presents the methodology and some of the results of accurate solution of the forward problem in magnetic-field tomography based on magnetoencephalography for brain imaging. The solution is based on modeling and computation of magnetic-field distribution in and around the head produced by distributed 2-D cortical and 3-D volume lead current sources. The 3-D finite-element model of the brain incorporates realistic geometry based on accurate magnetic resonance imaging data and inhomogeneous conductivity properties. The model allows arbitrary placement of line, surface, and volume current sources. This gives flexibility in the source current approximation in terms of size, orientation, placement, and spatial distribution.

For CompMechLab it is the fourth victory in ANSYS Image contests (2003, 2004, 2008 and 2009). This is a unique achievement among 79 winning companies in 2002-2009. 

Only four companies of 79 are three-times winnes:
- EMT R (Russia, 2005, 2006 and 2009),
- Dyson (Great Britain, 2002, 2004, 2007),
- Mouchel (Great Britain, 2003, 2004, 2005) 
- TriVista Engineering (Great Britain, 2003, 2004, 2006).

No other Russian companies except CompMechLab and EMT P may be found in the list of 79 winners in 2002-2009.
