CIVx is a free advanced PIV (Particle Imaging Velocimetry) code, developped in Fortran and C++. Input : pair of png images. Output : velocity field in NetCDF format. It is used by the UVMAT Matlab code develloped at LEGI.

Features

  • Spatial decoupling of the pattern box in image a from its counterpart in image b
  • Arbitrary grid definition by user or mesh generator
  • Advanced mask implementation
  • Correlation multiplication to reduce spurious vectors
  • Iterative CIV, taking into account pattern deformation by strain and rotation.
  • Adaptative continuous window shifting to reduce peak-locking effect
  • Image distortion
  • Numerical computation can be used as first guess
  • Standard file format for easy integration with third party solutions.
  • User defined criterions for false vector removal
