Patent ID: 7324103

Claim:
A system for direct mesh manipulation of a mesh model for the computer-assisted design of a product comprising: a computer system, wherein said computer system includes a memory, a processor, a user input device and a display device; a computer generated geometric model stored in said memory of said computer system, wherein said model is in a computer-aided design (CAD) format; and a user using the computer system to convert the CAD model into a mesh model, and iteratively evaluate the mesh model until a predetermined response is generated by performing a computer-aided engineering (CAE) analysis of the mesh model, modifying a design parameter based on the CAE analysis, and updating the mesh model to include the modified design parameter by direct mesh manipulation of a surface of the mesh model using Dirichlet parameter distribution to determine deformation of the surface of the mesh model, so that the evaluation of the mesh model is used in the design of the product.
