CAE Engineer, SACMI Imola S.C.
Riccardo Cenni received his Master’s Degree in Energetic Engineering at University of Bologna in 2012. After a one year internship in Alstom Power, he joined SACMI Imola S.C. where he is currently working as CAE Engineer at Ceramic Engineering Department. Currently 3rd year PhD student at University of Modena and Reggio Emilia (Italy) in the field of structural optimization.
Shape optimization is a way to improve the structural performance of components and tools based on parametric geometries are becoming standard for fine-tuning optimization in industry. Direct update of nodal positions of finite element models by mesh morphing is a meaningful alternative to re-meshing a parametric geometry, helping the designer in what-if studies, optimization and robust design development without geometry coherence problems.
There are some cases where FE loads depend on the geometric features on which they are applied or, on the other side, the analyst could want to strictly control the geometric features of the component. Geometry features can be controlled with mesh morphing, but in general, it is much easier and intuitive to direct control them with parametric geometries. On the other side geometry coherence can be a too strong limitation that inhibits any optimization of it. A different approach to mix the goods of both the techniques and overtake their limitations is proposed together with its application.
The proposed methodology is based on the main idea that the optimization is a mesh-based optimization driven by a parametric geometry. ModeFrontier potentialities are exploited to manage the optimization loop while RBF Morph is used to perform mesh morphing. Thanks to the proposed methodology different shapes can be obtained and analyzed according to internal procedures in order to speed up the design selection process.
