Shape Optimization of a Shell in Comsol Multiphysics

Optimization calculations are currently an actual and in-demand direction of computer-aided design. It allows not only the identification future characteristics object, but also implementation its exact model using a set various optimization algorithms. The advent digital modeling has significantly facilitated approach to methods. Many software systems equipped with capabilities for calculating design, finding optimal variant. calculation programs can include special module that be based on one or more mathematical purpose present study is explore process shape through two shells: simple (spherical dome) complex (helicoid) in Comsol Multiphysics three methods: MMA, SNOPT IPOPT. Additionally, attention paid construction mesh types selected element sizes: finer fine. Then, important task compare obtained results find most method effective design solution each shell. When sphere, suitable was IPOPT method, help which it possible achieve reduction dome along z-axis. helicoid, all methods showed approximately same values equally changed angle inclination surface relative horizontal plane.
