The main improvements are the presence of importers/exporters from and to both Ansys and Abaqus, which are likely the two most used commercial FE packages, and the availability of test data, including a full proximal femur.

Detailed release notes:

Importers/Exporters:
• Interface (Importer/Exporter) with Abaqus file format (this is the first fruit of a joint collaboration, with Elise Pegg at University of Bath)
• Importers/Exporters can also handle submodels (components/assemblies)
• Simplified generic mesh format for import/export
• VRML exporter
• VTK export supporting mesh rototranslation
Documentation (see also download):
• Small test data (10 elements) for debugging purposes
• Large test data (whole proximal femur, fully anonimysed)
Core application:
• New operation to merge meshes
• Copy and Paste now holds the position of meshes/volumes
GUI:
• New icons for meshes/volumes and Toolbar
• Icons added on Menu
Views:
• Clearer drawing of mesh edges
• Added mesh visualisation options

With the following major improvements:

Interactive GUI:
• Combined CT and FE model visualisation, perspective and slice views, contour maps...
Import/export of FE models:
• From/to one of the most used commercial FE packages (read in input by many others)
• From/to a generic mesh format (nodes and element connectivity matrices)
Algorithm rationalisation:
• Fewer lines of code
• Improved flexibility of the numerical integration function
• Simplified access to data structures
Performance:
• Import/export of FE meshes in few seconds
• Interactive visualisation of CT images and FE models
• Handling over 1M elements on a regular PC (4GB RAM)
Documentation:
• User Manual and FAQs now available
