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