ViziFlow

ViziFlow is a program designed with the objective of intuitive and rapid model creation, equally rapid calculation and display of streamlines and pressure profiles. As an aid to measurement, a flow rate and pressure gauge function is provided.

The first three toolbar icons have the usual functions of NEW FILE, OPEN FILE and SAVE FILE. When the application is first opened, the drawing area comes up in NEW FILE mode, with a grid pattern of dots and center lines. The TOOLS menu can be used to apply a line grid, or remove the grid and center lines. TOOLS - PREFERENCES can be used to define the default state when the application is next run. Help panels display when functions are selected, and an instruction line shows during object entry or editing.

To enter objects on the drawing area, first select an object type from the EDIT menu or toolbar. After selecting a rectangle or circle object type, click and release the mouse button to define the first object point on the screen. Then move the mouse to the next point (a black line or circle will be drawn, following the mouse pointer). Click and release the mouse button to define the next point. Simply repeat until all points are complete.

Viziflow can be as a teaching aid to demonstrate the principles of fluid flow in pipes or aerofoils and can also be used for simple measurements.

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.
