MID-SURFACE EXTRACTION FOR FINITE ELEMENT ANALYSIS

摘要

An apparatus is provided for implementation of a mid-surface modeler including a receiver, selector, clusterer and mid-surface constructor. The receiver is to receive a solid model of a structural product composed of structural components, with the solid model representing the components by a collection of geometry. The selector is to select a group of geometry from the geometry in the solid model, with the group of geometry having approximately the same shape, and being perpendicular to an axis of a local coordinate system. The clusterer is to cluster geometry of the group of geometry into one or more clusters of geometry based on a relationship between the geometry, with each cluster of the cluster(s) representing a component of the component(s). And the mid-surface constructor is to construct a mid-surface model of the product, including computation of respective one or more mid-surfaces for the cluster(s).

1. An apparatus for implementation of at least a mid-surface modeler, the apparatus comprising a processor and a memory storing executable instructions that in response to execution by the processor cause the apparatus to implement at least:
a receiver configured to receive a solid model of a structural product composed of a plurality of structural components, the solid model representing the plurality of structural components by a collection of geometry; a selector configured to select a group of geometry from the geometry in the solid model, the group of geometry having approximately the same shape, and being perpendicular to an axis of a local coordinate system in which the solid model is defined; a clusterer configured to cluster geometry of the group of geometry into one or more clusters of geometry based on a relationship between the geometry, each cluster of the one or more clusters representing a structural component of the one or more structural components; and a mid-surface constructor configured to construct a mid-surface model of the structural product, including the mid-surface constructor being configured to compute respective one or more mid-surfaces for the one or more clusters.
