PE logo Welcome to Process Evolution, Ltd.
(via process-evolution.com)
We are IC manufacturing process simulation experts, with hundreds of relevant publications and presentations.
   See EVOLVE, EVOLVE 3D, and/or Timothy Cale's Academic CV.
We developed unique interface tracking software we have used to thermal stresses in 3D-ICs.
   See below and/or EVOLVE MM.
We welcome ideas for applications/projects in any field, e.g., PV, 3D printing, medicine, biotechnology . . .
   Please Contact PE with your ideas and questions.

NEW Interface Extraction Tool
for EVOLVING Multiple Material Structures
Returns Consistent FEM Meshes!!
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 between material 4 and the others, and between material 2 and materials 1 and 3. (Tilting forward and back a bit is done for some visibility.) Right (top-ish): FEM meshes generated from the surface meshes after 1 step (x-section, with material 2 invisible for visibility). The meshes were generated using tetgen, and are 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!
