MultiElement Airfoils 5.0 solves the compressible Euler & Navier-Stokes equations for arbitrarily placed objects in subsonic, transonic and supersonic flows. It is a turn-key product that eliminates grid generation hassles and accurately computes lift, drag and moments for a group of airfoils and individual airfoils within the group.

Summary

MultiElement Airfoils 5.0 solves the compressible Euler & Navier-Stokes equations for arbitrarily placed objects in subsonic, transonic and supersonic flows. It is a turn-key product that eliminates grid generation hassles and accurately computes lift, drag and moments for a group of airfoils and individual airfoils within the group. MultiElement Airfoils displays graphs of pressure, Mach number, temperature and total pressure using built-in post processing tools (it does not require additional third party software for pre or post processing). It is an excellent tool for optimizing cross-sectional shapes and getting the correct placement of aerodynamics components for aircraft, automobiles, boats, house hold products and other equipment.

Benefits

Benefits

  • Analyze complex airfoil shapes and apparent wind angles of 360 degrees (most airfoil analysis software do not analyze past an angle of attack of 20 degrees).
  • Ideal for Savonius and Darrieus types vertical wind tunnel blade analysis.
  • Solve conflicting wing design problems that call for high lift at landing and takeoffs but low drag and efficiency in the cruise configuration.
  • Solve the problem of generating high lift when the wing dimensions are fixed by the rules of the competition.
  • Analyze multiple airfoils shapes without the hassles of grid generation. Just drag the airfoils into place (or enter their exact location), size and rotate them and click the menu to automatically generate your grid.
  • Accurately solves compressible Euler & Navier-Stokes equations for for multiple airfoils and other 2-dimensional shapes.
  • Understand the behavior of airfoils used in the design of wings, helicopter blades, hydrofoils, fans, propellers and other equipment.
  • Understand and make critical design decision in transonic & supersonic flow regime.
  • Easy-to-use tool for designing more efficient wing & machine blade cross-sections.
  • Eliminate steep learning curve for new engineers & reduce training costs.
  • Windows based interfaces requires little or no training.
