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.
