Sandia National Laboratory
Cubit External Review Session

12:15PM-5:30 PM (Wednesday)

Following the regularly scheduled events at the International Meshing Roundtable, Sandia National Laboratories will be hosting its annual Technical Review. This event will be open to the public. The CUBIT Geometry and Mesh Generation Toolkit has been funded by the US Department of Energy and developed by Sandia for over a decade. In addition to supporting a user-base of 100’s, it also serves as a framework for new geometry and mesh generation algorithms and research. The purpose of the Technical Review is to present current research and development activities currently underway in the CUBIT team and to solicit feedback from other experts in the field. This will be an informal forum where CUBIT developers will present aspects of their current research and development activities. Following the open session, a panel of invited experts will be asked to provide formal recommendations to the CUBIT team. The results of the panel will be considered in setting future directions for the project.
