PIV analysis software [Flownizer II]

2D/2D3C PIV software

Flownizer II 2D/2D3C [Particle Image Velocimetry]

Flownizer is PIV software that was developed in Japan and being used by various researchers in worldwide.

Its friendly interface and high processing speed allow users to make their workflow smooth and time-efficient.

Now, with the addition of new features and new analysis items, it has been reborn as Flownizer II.

Experience the new and improved Flownizer II with its ease of use and clarity remaining unchanged.

Flownizer II 2D/2D3C

Intuitive interface with tree structure. Three modes: 2D PIV, 2D PTV, and Stereo PIV (2D3C).

Equipped with diverse features such as correlation coefficient maps, masking, and various image preprocessing options.

 

Key Features【Settings】

Correlation coefficient map

Set the template size and search range which will have the most

significant impact in the measurement results.

Even beginners in PIV can find and set optimal parameters effortlessly and smoothly.

Both spatial and temporal analysis can be conducted through an easy-to-use interface.

 

【Results Display/Data Output】

Vectors, Contours and Streamlines Display

You can generate and select raw vectors, average vectors, interpolated vectors, and smoothed vectors. It is possible to overlay and adjust the transparency of streamlines, pathlines, and streaklines. The visualised data can be exported as CSV files.

Graph Display

Graphs for each profile will be displayed on the horizontal axis. An animation will be shown in sync with the video playback.

Convenient functions

Project Data Comparison

Load multiple PIV projects. Selecting vectors generates graphs comparing velocity changes.

Batch Processing

Analysis settings from a reference project can be applied to other projects, significantly reducing processing time.

Simple Report Output

Generates simple reports that can be edited in Excel.

FFT Analysis

Calculates power spectral density using Fourier Transform.

Flownizer II version comparison

※2D3C includes the functionality of 2D version.
※2D version can be upgraded to 2D3C for an additional cost.
