Prana is one of three software programs for PIV analysis being demonstrated at the UMD Burger's Program for Fluid Dynamics joint PIV Workshop. Topics in the demo included the difference between RPC and standard cross-correlation, and the effect of signal to noise ratio, shear, and processing on the correlation planes.

Major changes are the addition of PTV, iterative processing per pass, handling of multiple color channels, and many others and bug fixes. See the change log in the release notes for details. Download now!
