2nd Workshop « 3D Microtexture analysis » Metz, October 13-15, 2015
Advanced Session « Development of plugins in Dream3D » Metz, October 16, 2015

LEM3 « Laboratoire d'Etudes des Microstructures et de Mécanique des Matériaux » – Université de Lorraine – CNRS will host the 2nd workshop on 3D Microtextures in collaboration with the Air Force Research Laboratory (AFRL), BlueQuartz Software and the Materials Science & Engineering Dept. at Carnegie Mellon University.

The workshop is intended to provide researchers at all levels with tools and methods for reconstructing, analyzing and synthesizing 3D microstructures. A particular focus of the methods is on the use of crystallographic orientation (texture), whether for reconstructing a 3D volume from EBSD serial sections, or for generating representative microstructures with orientations assigned for each grain. This 2nd session includes invited lectures on relevant topics and hands-on exercises on provided computers to explore the novelties offered by the last version of Dream3D* (Version 6**).

The main topics are:

  • Preprocessing of data: Import, Alignment, corrections...
  • Data Analysis: Morphological and crystallographic descriptors of grains and boundaries
  • Analysis of Grain Boundaries Character Distribution
  • Coupled analysis of EBSD and Imaging data in Dream3D
  • Generation of Synthetic 3D microstructures
  • Application to mechanical properties assessment using FFT simulations
  • Meshing and smoothing microstructures
  • A dedicated session to be coached for analyzing your own dataset on your laptop only

Confirmed invited speakers are:

  • Mike Groeber, US Air Force Research Laboratory, USA
  • Anthony Rollett, Carnegie Mellon University, Pittsburg, USA
  • Sean Donegan, Bluequartz, USA
  • Dave Rowenhorst, Naval research Laboratory, USA (web-session)
  • Ken Mingard, National Physical Laboratory, UK
  • Frank Mücklich, Üniverstität des Saarlandes
  • Guillaume Stechmann, Max Plank Institut Düsseldorf, Germany

For those who are interested in programming their own filters, the workshop continues with an advanced session dedicated to the development of Plugins in Dream 3D (apart registration).

*DREAM.3D is a freely available software package that performs a wide range of functions for reconstructions of 3D microstructures, statistical analysis and generation of representative volume elements. The standard input is a stack of orientation maps such as EBSD maps from serial sectioning or synchrotron data sets. The package is tightly integrated with Paraview, which is a freely available visualization software that, like Dream.3D, runs on all standard computers.

**Version 6 Additions

  1. vastly improved image processing capabilities - still growing
  2. new geometries for data - 2d quad meshes, variable x,y,or z thicknesses for voxel stacks, point clouds, line segments, tet meshes coming soon
  3. clean-up tools expanded and generalized from TSL EBSD specific algorithms
  4. many general data manipulation tools for performing logic operations on data
  5. expanded crystal systems to all symmetries and moved to consistent orientation transformation library
  6. added auxiliary tool to generate skeleton code for new filters and plugins - lowering barrier to development
  7. repaired >100 bugs/inconsistencies/memory leaks
  8. GBCD now works for multiple phases and for all symmetries
  9. many advances in synthetic building tools
  10. links added to export structures to Abaqus and FFT code
  11. plugin to fuse data sets from different sources
  12. plugin to perform introductory analysis of dislocation dynamics simulations
  13. filter to calculate GND density (Nye tensor) from 3d EBSD data
  14. filters for sampling surface meshes to move between interface and volume representation
  15. new visualization filters for improved visual interrogation of data
  16. filter to extract features of interest into individual sub data sets
  17. improved GUI with many ease of use additions - document model for having multiple pipelines open at once
  18. vastly improved documentation
