Automatic Finite Element Mesh Generation for the Automation of Parametric Conceptual Design 912219

An approach for the automatic generation and refinement of three dimensional finite element meshes subdivided by rigid body movable subdomains has been developed. A combination of computational geometry and geometric modeling techniques have been employed to implement parametric computer-aided design based on the finite element method. To demonstrate the utility of this approach to parametric redesign, a series of meshes that model a hip joint prosthesis and a reciprocating internal combustion engine have been generated.
