Capstone: A Geometry-Centric Platform to Enable Physics-Based Simulation and System Design

Capstone is a geometry-centric platform for a unified representation of the geometry, mesh, and attribution needed for engineering analyses with varying fidelity. Meshes and attributes are both associated with a robust mathematical model of the geometry, enabling any change to be automatically propagated to the meshes and attributes needed for analyses. Captsone provides a software platform with well-abstracted and compact interfaces to create, modify, and query geometry, mesh, and attribution information for a model. This forms a foundation for geometry-based design environments and solvers that can access the geometry at runtime for scalable and accurate a posteriori mesh adaptation. Capstone provides a graphical front end for computational fluid dynamics. Capstone is being used and evaluated by several US Department of Defense organizations.
