Shape Optimization by Particle Swarm Algorithm Utilizing Isogeometric Analysis
Original language description
The present paper describes the application of the particle swarm optimization (PSO) to the shape optimization of two-dimensional domains described by NURBS and analyzed by the NURBS-based Isogeometric analysis. The regularization of the optimization problem, preventing undesirable clustering of control points of the underlying geometry leading to invalid geometry or parametrization, is achieved by controlling the magnitude of perturbation of design variables within PSO using a background mesh. This mesh, however, does not have to comply with requirements on a standard (e.g. FEM) computational mesh, as it does not have to follow the exact geometry. Thus construction of such mesh (Matlab Distmesh tool is utilized) is simple and does not introduce a bottleneck to the whole process. The capabilities and performance of the developed optimization strategy will be demonstrated on a standard benchmark problem.
