System and method of applying geometric surface features to volumetric CAE mesh models

摘要

A CAE mesh modeling system and method for use with a CAE mesh morphing software system to interactively determine a deformation of design mesh models selected from solid meshes, multiple layers of surface meshes, or a combination of each using a base model and defined deformation features. The methodology advantageously defines a volumetric region of the model for modification, maintains a smooth transition between the volumetric region and the rest of the model, and simultaneously modifies all nodes and associated projected nodes within the affected volumetric region in a controlled manner. A new deformation volumetric model feature is created which includes the deformed base model. The methodology takes advantage of similarities between models by treating a set of mathematical operations associated with each mesh deformation as an independent entity that can be stored separately and reapplied to deform another model at another time.
