TN7 is aimed towards developing a "virtual wind tunnel" for artistic visualizations of fluid flows. It is based on the library MSAFluid by Memo Akten, a 2D fluid solver based on Jos Stam's programmatic implementation of the Navier-Stokes equations describing the motion of fluid substances.

The application builds on the library's functionality by adding definitions and behavior for solid linear obstacles and linear thrust manipulators. These objects interact with the motion of the fluid, altering it according to their type, position and orientation.

In TN7, a simple drafting interface is used to draw the elements. Then, a visualization of the velocity field of the fluid around the objects is presented. The user may choose to display a 2-D vector impression of the field or a 3-D heightfield impression, generated from the magnitudes of each vector. The latter can also be exported as a 3-D model in .DXF format for importing in CAD applications.
