Objective
The University of Iowa has developed a complete Finite Element meshing workflow to operates from image source through to FE simulation using Abaqus. For this project, we are will be creating new Slicer3 execution model programs to support the meshing workflow and to expand the current meshing capabilities.
Approach, Plan
Two tools will be developed to help support the meshing workflow. This includes the following:
- Material property assignment for mesh elements using imaging data
- Tool to export VTK unstructured grids to the Abaqus format.
Progress
June 2007 Project Week
Discussion of meshing improvement packages. Drafted an effort with Sandia Labs to test the Mesquite mesh improvement library for biomedical mesh applications. Discussed licensing issues with NA-MIC regarding external libraries. Specific accomplishments this week:
- Integrated a rigid body initialization for a Thirion Demons registration for atlas <-> subject registration. The above modification was used to warp the atlas to the subject as shown in the figures.
- Neural network code now supports all ITK transforms for registration of the atlas<->subject. This was achieved using the itkTransformReader and the a templated function over the image type and transform type to resample the images.
Jan 2007 Project Half Week
Completed a command line module to perform voxel meshing in Slicer3. Developed VTK-based algorithms for creating triangulated surface representations with embedded holes.
