Mesh-based shape optimization systems and methods

摘要

A system and method for shape optimization that includes receiving information regarding a model that represents one or more physical objects to be manufactured, the information comprises a finite element mesh, geometric parameters, geometric constraints, and manufacturing constraints of the model and generating a morphed mesh that results in an updated finite element mesh in order to meet specified model characteristics. The method further includes generating the morphed mesh by displacing nodes located at the boundary regions of the model and determining a displacement of interior nodes of the finite element mesh using an interpolation of boundary node displacement.

1. A method for shape optimization, comprising:
receiving information regarding a model that represents one or more physical objects to be manufactured, the information comprises a finite element mesh, geometric parameters, geometric constraints, and manufacturing constraints of the model; generating a morphed mesh that results in an updated finite element mesh in order to meet specified model characteristics; wherein generating the morphed mesh comprises:
displacing nodes located at boundary regions of the model;determining a displacement of interior nodes of the finite element mesh using an interpolation of boundary node displacement;moving boundary nodes of the finite element mesh using a displacement vector representative of geometric inconsistencies; andmoving the interior nodes to new positions by adding the displacement vector to coordinates of the interior nodes.
