gpivtools-mpi binary package in Ubuntu Trusty i386

 A collection of programs for images that are generated
 during a Particle Image Velocimetry (PIV) experiment. This is a
 technique to obtain the velocity field of a fluid flow quantitatively
 and is performed by tracking tracer particles that have been seeded
 to a fluid. The technique is also applied for observing deformations
 at surfaces of (solid) bodies. The package contains:
  * an image processing program for typical filtering and manipulation
    routines that may be convenient for PIV.
  * an image interrogation program resulting into estimators of particle
    image displacements.
  * validation programs to test on outliers, peak-locking effect and
    velocity gradients.
  * post-processing programs for data manipulation (flipping, rotation
    etc), spatial and time scaling, calculation of spatial averages and
    derivative quantities from the PIV data, like vorticity and strain.
  * miscellaneous programs and scripts to perform image format conversion,
    batch-processing, pipeline processing (image evaluation, validation and
    post-processing at once), calculation of time averages from a series
    of PIV data sets, data-visualization and data-manipulation.
 .
 This package contains the MPI-parallelized programs for use on
 a (Beowulf) cluster. All programs start with gpiv_.
