Ring vortices in a pulsed jet flow. The iso-contours represent the Q-criterion.

The DynamicStudio Volumetric Velocimetry Add-ons provide a large variety of analysis methods, including tomographic PTV providing Lagrangian trajectories of particles paths, as well as Least Squares Matching routines for high resolution velocity data in a regular grid.

In addition, the software has numerous advanced tools that simplify and guide the user throughout the measurement and analysis procedures

  • Tools and support guides for every stage from planning the measurement to the final visualization
  • Ability to generate volumetric results from a two-camera solution
  • GPU acceleration for faster processing
  • Volumetric Calibration Refinement and fully automated calibration tools
  • PIV Challenge tested

Tomographic PTV processing highlights

PTV Track Smoothing

The smoothing parameters are controlled by the sliders at the left side

PTV tracks often appear jagged because of noise in the raw images leading to uncertainties in the estimation of the particle position.

Some kind of smoothing of the tracks is therefore useful prior to postprocessing.

In DynamicStudio, you can apply Radial Basis Functions (RBF) to smooth 2D or 3D particle tracks.

Ensemble PTV

Get time averaged velocity data with high spatial resolution from PTV data.

With Ensemble PTV it is possible to obtain turbulence statistics with high spatial resolution even from sparsely seeded flows. 

Velocity vectors from the individual PTV time steps are added up resulting in a time averaged, high density vector map, from which turbulence statistics are derived.

The achievable spatial resolution depends on the density of the vectors in each time step, and on the number of time steps recorded.
