NEW Interface Extraction Tool
for EVOLVING Multiple Material Structures 		Interfaces WF Animation
Initial Stack WF Initial + Final FEM mesh step 1, no material 2
Initial Stack Exploded Final Stack Exploded Interfaces Views
Left (top): Wireframes for materials 1-3 and surface mesh for material 4, for visibility. (bottom) Exploded view of initial structure, indicating materials.
Center (top): A x-section showing the final surface meshes, and initial x-section (gray) of material 4. (bottom) Exploded view of evolved structure.
Right (very top): Animation of the evolution of the interfaces: those between material 4 and the other materials, and those between material 2 and materials 1 and 3. (Tilting forward and back a bit is done for some visibility.) Right (top-ish): FEM mesh generated from the surface meshes after 1 step (x-section, with material 2 invisible for visibility). The mesh was generated using tetgen, and is ready to be used by FEM codes for further computations of evolution speeds. (middle): Still shot of interfaces during the evolution of the multiple material structure. (bottom): "A" tags interfaces between 2 materials. "B" tags interfaces between 3 materials. The New Contribution!

We are looking for projects on which to demonstrate the application of the new method to more complicated problems. See other pages/links, even the "archival" pages PLENTE and EVOLVE, for examples.
