Abstract Scope |
Diffuse interface methods (DIM) such as phase field (PF), are attractive due to their implicit boundary representation and ability to robustly incorporate multiple physical phenomena. The primary limitation of DIM is its computational expense resulting from the fine grid size required to correctly resolve the boundary. Block-structured adaptive mesh refinement (BSAMR) was originally developed for fluid mechanics, but offers an attractive computational framework for accelerating DIM-type simulations. The implementation of explicit DIM is relatively straightforward, but implicit uf (such as solving mechanical equilibrium) are more complex and require a novel approach. In this talk we discuss the details of both explicit and implicit methods for DIM and BSAMR, and demonstrate the application of the methods to a variety of mechanics and materials problems. |
