A program to allow the very fast modeling of fluid flow, and the visualization of the streamlines and pressure distribution. Rectangular and circular sections can be entered as well as aerofoils. Example files are included, and many editing tools are provided. A website gives a message board to exchange views.
this is an interesting small prog. i used it to demonstrate airflow around a simple airfoil.
Thing is this, it says free license (at download.com) but when you install it, it is free-try for 30d. they want $9.95 after that. i wish they'd have been upfront with that. otherwise an interesting demo.
