Efficient preconditioning techniques for phase-field models

Thursday, May 10, 10:00 – 11:00 AM

ABSTRACT: In order to avoid interface conditions and enable the use of a fixed mesh in time-dependent problems,it is shown that a diffusive model of Cahn-Hilliard type can be used. SOME NUMERICAL EXAMPLES ILLUSTRATE THE METHOD. A preconditioning method is used that needs no update.  Efficient implementation on parallel clusters are shown.
