Updating A CAD Model To Reflect Global Or Local Shape Changes

A system for updating a computer-aided design (CAD) model, the system comprising:

• a parameterization module configured to generate a parameterization of each respective face of at least one finite element analysis (FEA) model, each respective face of the at least one FEA model corresponding to a respective geometric face of a computer-aided design (CAD) model to be updated and each face of the at least one FEA model having a respective shape;
• a shape function module configured to determine a respective shape function for at least one face of the at least one FEA model using the respective shape of the at least one face and the corresponding generated parameterization of the at least one face, the determined shape function describing the shape of the at least one face of the at least one FEA model;
• and
• an update module configured to update the CAD model using the determined shape function.

A non-transitory computer readable medium having stored thereon a sequence of instructions which, when loaded and executed by a processor coupled to an apparatus, causes the apparatus to:

• generate a parameterization of each respective face of at least one finite element analysis (FEA) model, each respective face of the at least one FEA model corresponding to a respective geometric face of a computer-aided design (CAD) model to be updated and each face of the at least one FEA model having a respective shape;
• determine a respective shape function for at least one face of the at least one FEA model using the respective shape of the at least one face and the corresponding generated parameterization of the at least one face, the determined shape function describing the shape of the at least one face of the at least one FEA model;
• and
• update the CAD model using the determined shape function.
