Hello, A yearly allocation for the LCRC cluster has been requested with the following updated information: Submitter/PI: lei wang Project Name: DVI_Materials Division: MCS Project title: DVI Solvers for Material Science Associated funding: DOE ASCR ARPA-E, FASTMath SciDAC Other Systems: Science: This project uses differential variational inequalities (DVIs) for heterogeneous materials problems, which describe the mesoscale behavior of irradiate damaged materials, for example in a nuclear reactor. The phase field approach is used for modeling microstructure in the mesoscale. Since the diffuse boundary between phases must be localized, one needs to use double obstacle potentials for generating the free energy functional. This results in a differential variational inequality. Our aim is to develop algorithms and software for large-scale DVIs in collaboration with material scientists.
