Toward Automated Topology Optimization: Identification of Non-Design Features of CAD Models Using Graph Neural Networks
摘要
This paper presents an automated identification of non-design features of CAD models for topology optimization using learning-based segmentation. The CAD files are taken from a large database of industry-relevant components. Based on the geometry and topology of the components, a graph structure is created and processed by a deep neural network. The results show good match with real cases and can be continuously improved by training with additional data.
