| DWPI Title: System for fabricating a body, comprises a processor for executing programming and a non-transitory computer-readable storage medium encoding with the programming for creating complex geometry configuring to receives a mapping of a body |
| Abstract: Systems, methods and computer program products for creating 3D representations of bodies are disclosed. The systems, methods and computer program products include the construction of FE meshes representing complex geometries. The complex geometries may be artificially or naturally formed or designed geometries. The techniques reduce the number of elements as much as possible to save on computer run time while maintaining computational accuracy. |
| Use: System for fabricating a three-dimensional body in a finite analysis shape modeling. |
| Advantage: System for fabricating a three-dimensional body in a finite analysis shape modeling that provides an accurate transfer of measured solid-body nodal points to a computational mesh consisting of hexahedral finite elements that maintain the integrity of the original measured geometrical data, and constructs hex mesh elements that have the required characteristics for efficient, accurate, and stable calculation. |
| Novelty: The system comprises a processor for executing programming. A non-transitory computer-readable storage medium, encoded with the programming for creating complex geometry. The non-transitory computer-readable medium with programming is configured to receives a mapping of a body. A finite element mesh representation of the body is created that includes, the body divided into slices. An element is created within the slices. The adjacent layers of elements are connected by common nodes. A manufacturing system that receives the finite element mesh representation of the body and manufactures a portion based on the created finite element mesh representation of the body. |
