MicroCFD®
Virtual Wind Tunnel

MicroCFD analyzes 2-D 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 runs out of Microsoft Windows through simple "point and click" operations, which are outlined in an easy-to-follow tutorial. While the program is computing, other applications can still be run with minimal sacrifice in performance. Any screen output can be sent to a color printer.

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 quasi-steady state within a few hours on a system with minimum requirements.

MicroCFD can model vehicles in ground effect through a 2-D simulation of flow along their centerline. Bodies of revolution such as spheres, bullets, or space reentry vehicles are tested in axisymmetry mode. Airfoil cascades can be set up for compressor or turbine blade profile analysis.

MicroCFD is downloaded in 5 minutes using a 56 kbit/s modem. The 1.72 MB installation file is a compressed, self-extracting executable, which will guide you through the setup of the program and all supporting files. The software can be run free for a trial period of three days. There is no obligation to buy!

MicroCFD is an excellent educational tool for anyone studying aerodynamics, computational fluid dynamics, gas dynamics, or compressible flow. Educational institutions can purchase multi-user licenses for their students at a discount rate, either as part of an onsite installation or for individual use.

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). All other features are identical between the two editions.
