v5 v6 7 7 Our recent work on higher-order accurate unstructured mesh finite volume methods has demonstrated that high-order methods are at least as efficient in CPU and memory use as second-order methods in computing solutions to simple problems in transonic aerodynamics. We are currently working to extend these results to three-dimensional, turbulent flows. In addition, because our high-order flow solver is more efficient than second order flow solvers, we expect --- and are working to demonstrate --- that our higher-order optimization scheme will also be more efficient than a corresponding second-order scheme. 8 8 9 == [ wiki:GRUMMP Unstructured Mesh Generation] ==9 == [http://tetra.mech.ubc.ca/projects/GRUMMP Unstructured Mesh Generation] == 10 10 11 11 As computers and solution algorithms continue to improve, the problem of mesh generation and adaptation becomes even more of a bottleneck in numerical simulation. Our goal in this area is to continue to reduce human input from the process by enabling automatic generation of high-quality isotropic meshes from CAD data, nearly automatic anisotropic mesh generation and automatic anisotropic mesh adaptation based on local error. In addition, we are working with the Interoperable Tools for Advanced Petascale Simulations (ITAPS) consortium in the US to develop a standard interface for interaction between solution algorithms and mesh data, both in serial and in parallel, to reduce the burden on application programmers to adopt new techniques in mesh generation and adaptation.
