Virtual Wind Tunnel

    MicroCFD analyzes 2D and axisymmetric subsonic, transonic, and supersonic flow (Mach 0.1 to 10) over multi-element configurations on a Cartesian cut-cell mesh. Flow visualization is provided through color maps of local Mach number, density, pressure, and temperature, including streamline plots. An aerodynamic force line instantly reveals the center of pressure of any configuration.

    MicroCFD can model vehicles in ground effect through a 2D simulation of flow along their centerline. Bodies of revolution such as spherical projectiles, bullets, space capsules, or rocket nozzles are tested in axisymmetry mode. Airfoil cascades can be set up for compressor or turbine blade profile analysis, and both supersonic ramp and spike inlets can be modeled. The free nanoCAD allows for easy geometry creation and DWG / DXF imports.

    MicroCFD is based on a finite volume description of the unsteady Euler equations and can capture both steady and moving shock waves. A solution is marched in time from an instantaneous acceleration of the flow and converges to steady or periodic state within an hour on a system with minimum requirements. On systems with multi-core processors or CUDA enabled NVIDIA graphics cards, a wind tunnel test will complete in minutes.

    MicroCFD runs on Microsoft Windows via simple "point and click" operations, which are outlined in an easy-to-follow tutorial. A two-part narrated instructional video shows its simplicity. The software has been validated through experimental data in 2D (NACA airfoil) and axisymmetric (G7 bullet) flow studies and has been put to the test by a diverse number of clients in academia, government, and industry.

    MicroCFD is available in two editions. The educational edition of the Virtual Wind Tunnel has a flow resolution of 800x600 (480,000) cells, whereas the professional edition runs at 1250x800 tunnel resolution (1 million cells) for more accurate results. The professional edition can run multiple tests in a batch and generate a summary text file of all the relevant aerodynamic data.

    MicroCFD is downloaded in less than a minute. The 2.6 MB installation file is a compressed, self-extracting executable, which will guide you through the setup of the program and all supporting files. Each edition of the software can be run free for a trial period of three days. There is no obligation to buy! Multi-user and multi-year licenses are available at a discount rate.

    MicroCFD professional edition licenses (Version 1.8) will be upgraded to the upcoming 3D Virtual Wind Tunnel, which is expected to be released in the second half of 2014. The 3D version currently under development will use STL input files, a standard CAD format based on surface triangulation. A free STL Viewer with sample files is already available for download.
