An Automatic Post-Processing Procedure for Isogeometric Topology Optimization Results

In the intelligent structural optimization, designers can obtain a high-performance design scheme automatically with help of topology optimization (TO). Since computer aided (CAD) and engineering (CAE) models have different geometric representations in TO, optimized results must be reconstructed to generate CAD models, which is complicated time-consuming. To address this issue, isogeometric analysis (IGA) employed TO replace finite element method (FEM), such termed as (ITO). ITO an advanced high efficiency accuracy. It uses same non-uniform rational B-spline (NURBS) basis function both representation physical interpolation. However, due complex structures, automatic post-processing procedure for still challenging. solve problem,we present editable terms control points ITO. The takes variables high-dimensional coordinates points, reconstructs model by series algorithms surface/plane intersection algorithm, surface skinning, plane trimming algorithm. Therefore, result are boundary consisting skinned surfaces trimmed planes. proposed postprocessing full advantage ITO, breaks bottleneck integrating structure design, analysis, optimization.
