Fast solvers for phase field models




Project leader: Researcher: Duration: since January 2012

Project description:
Phase field models have a wide area of application such as in materials science to model coarsening in alloys, in image processing for image inpainting or in polymer science. These models are usually based on an energy functional depending on the phase field variable. The Cahn-Hilliard model is an example of a phase field model based on a diffuse interface. The underlying energy includes an obstacle potential. The model is usually formulated as a variational inequality of fourth order. We consider the efficient solution of various Cahn-Hilliard systems.
