Objective

We are developing methods generation of finite element meshes. This includes both semi-automated techniques using building blocks that can be manipulated with a number of new VTK widgets, and fully automated mapped meshing techniques. Our group is focused around the application of these tools to study orthopaedic biomechanics, but there are several other potential applications.


Approach, Plan

Work during the project week will continue much of the work that we have undertaken over the past year. Several integration projects will be tackled.

  1. Update existing voxel meshing execution model code. Bring it up to date with the changes that have taken place over the past six months with the base meshing code. Support now exists within Slicer3 for handling of unstructured grids and this should be propagated into this module.
  2. Work with Steve and Curt on changes to the meshing workflow.
  3. Work with Curt on unifying stand-alone and Slicer3 meshing code base.
  4. Discuss with KWWidgets developers some of the issues that exist in this toolkit
    • Multi-column list box scrolling issues
    • Notebook widget and potential for constant size tabs and scrolling tabs

Description

The Musculoskeletal Imaging, Modeling, and EXperimentation (MIMX) Program is a collaborative effort directed at computational modeling of anatomic structures. A primary objective is to automate the development of patient-/subject- specific models using a combination of imaging and modeling techniques, with particular emphasis on finite element modeling.
