About CREATE- FT

The Fundamental Technologies project was formed to improve the ease, speed, flexibility, and quality of geometry, mesh and attribution  modeling for physics-based computational simulations.  For DoD  weapons systems, it provides the ability to develop numerical  representations of geometry, generate meshes, and assign analyses attributes needed for use by  high-performance scalable solvers developed by  CREATE.​ Software: Capstone

Capstone is a software platform to create, modify, and query  geometry mesh and attribution information needed to define a numerical representation (digital  model) for physics-based simulation of complex engineering systems. Capstone applications include computation of complex flow fields around air-vehicles (fixed  and rotary wing), ships and submarines; analyses and design of radio-frequency  (RF) antennae systems; shock and damage modeling for ships and submarines; structural-acoustics and terrain modeling.

Capstone geometry capabilities include the ability to handle arbitrarily complex three-dimensional geometries using non-uniform-B-Splines (NURBS) curves and  surfaces. It supports full non-manifold geometry representations. The Capstone platform is agnostic to the details of geometry-system (CAD) due to the use of suitable abstractions for the needed geometric operations.

Capstone meshing capabilities include fully automated algorithms to generate unstructured anisotropic curvilinear meshes needed for a range of physics and  discretization techniques. It generates meshes needed for complex flow field with multiple interacting boundary-layers. Capstone generated meshes are tightly associated with the underlying geometry model, enabling geometry-based a-posteriori mesh adaptation.

Capstone attribution capabilities include attaching information to the model geometry in an associative manner where the attributes are automatically  updated as the geometry is edited. Coupled with the tight-association of the meshes with the geometry, this provides for robust and automated transfer of analysis attribution information to the meshes needed by the solvers.

The Capstone platform consists of a GUI-based application for traditional pre-processing workflows and analyses, as well as a powerful software development  kit (SDK) with well-abstracted, compact application programming interfaces (API). The SDK provides a foundational capability enabling geometry-based engineering design and analyses.
