Mesh Management

We’re developing fast and scalable algorithms for solving partial differential equations that dynamically adjust the computation mesh in order to improve accuracy and make the best use of computational resources. We research new methods for block-structured adaptive mesh refinement and high-order unstructured curvilinear mesh optimization, targeting applications with moving and deforming meshes. Our algorithms can be used to accurately represent the moving and deforming geometry as well as to resolve internally moving features such as material interfaces, shocks, and reaction fronts.

SAMRAI: Structured Adaptive Mesh Refinement Application Infrastructure

The Center for Applied Scientific Computing (CASC) at Lawrence Livermore National Laboratory is developing algorithms and software technology to enable the application of structured adaptive mesh refinement (SAMR) to large-scale multi-physics problems relevant to U.S. Department of Energy programs. The SAMRAI (Structured Adaptive Mesh Refinement Application Infrastructure) library is the code base in CASC for exploring application, numerical, parallel computing, and software issues associated with SAMR.
