Using Shape Optimization Settings in Comsol Multiphysics for Efficient Structural Design of Shells

Shape optimization is one of the most important types of structural optimization for spatial coatings (shells), in which the boundaries, shapes and contours of the object under study are changed while maintaining its original structure-topology without creating any holes in the model itself. Correct adjustment of the components of the optimization process in the program allows to get a truly optimal result, both from a constructive point of view and from an aesthetic point of view. The article is devoted to the configuration and interaction of two important parameters, which are situated in Shape optimization settings in the Comsol Multiphysics program: maximum displacement (dmax) and filter radius (Rmin) when optimizing the shape of two shells using the gradient method IPOPT (Interior Point OPTimizer). The purpose of the study is to select the most appropriate value of dmax and Rmin for two shells for finding the effective shape optimization decision.
