IMTreatment package

IMTreatment - A fields study package

This module has been written to carry out analysis and more specifically structure detection on PIV velocity fields. It is now more general and can handle different kind of data (point cloud, scalar and vector field, …) and perform classical and more advanced analysis on them (spectra, pod, post-processing, visualization, …).

General data analysis

  1. Class representing 2D fields of 1 component (ScalarField)
  2. Class representing 2D fields of 2 components (VectorField)
  3. Classes representing sets of scalar fields vector fields (SpatialScalarFields, TemporalScalarField, SpatialVectorField and TemporalVectorFields)
  4. Class representing profiles (Profile)
  5. Class representing scatter points (Points)
  6. Module for modal decomposition (POD, DMD) and reconstruction (pod)
  7. Module to import/export data from/to Davis, matlab, ascii, pivmat and images files (file_operation)
  8. Functionalities to visualize those data (plotlib)

Flow analysis

  1. Module to create artificial vortices: Burger, Jill, Rankine, … and to simulate their motion in potential flows (vortex_creation)
  2. Module providing several vortex criterions computation (vortex_criterions)
  3. Module to automatically detect and track critical points (vortex_detection)
  4. Module to compute the evolution of some vortex properties (vortex_properties)
  5. Module to generate potential flows with arbitrary geometries (potential_flow)
