Overview

Albany serves as a demonstration application of new libraries, advanced solution and discretization capabilities, and new software development methods focused towards challenging applications in computational mechanics.

As for the integration of Albany with SCOREC's MeshAdapt, two major steps were taken (1) Integration of SCOREC's GMI/FMDB with Albany: The development to transform geometric model/mesh data loaded in GMI and FMDB into Albany-compatible data structure which is based on exodus, is completed, and demonstrated in both serial and parallel regression tests. (2) The integration of SCOREC's MeshAdapt: The development is well underway. A template interface to the meshAdapt capability in Albany is completed and being tested; thus far two traits classes have been developed to demonstrate isotropic adaptation designed to maintain high quality finite elements during large deformation and material necking events.

The continuation solver (involving the Trilinos LOCA and Piro packages), was extended to support remeshing and solution transfer operations during an adaptive simulation. A generic, two way coupling to the meshAdapt classes results that supports the interplay between the continuation solver architecture and the mesh adaptation library. Two additional regression tests were added to demonstrate the adaptive continuation solver and generic interface; these tests run automatically as part of Albany's test suite.

The future work includes the definition of lightweight semantics to couple localized solution transfer and mesh adaptation operations, using Lie Algebras and capabilities with be developed to pose more general multiphysics error indicators using template classes. These two advances will be combined to demonstrate adaptive control of the mesh in areas near highly deforming crack tips.
