The Optimization Module in COMSOL Multiphysics provides tools for optimizing designs by finding the best combination of parameters to satisfy certain objectives or constraints. It’s commonly used in engineering and physics simulations to optimize designs for various applications. Besides the parameters sweeps and basic design parameters optimizations, it provides some automation for more complex optimization.
The first one is the traditional optimization for the design parameters.
The second one is the shape optimization. The shape optimization involves modifying the geometry of a model to achieve specific goals such as minimizing stress concentrations, reducing weight, or maximizing heat transfer. It can change shapes and generate the variable automatically.
The third one is Topology optimization. it is a type of optimization technique used to find the optimal distribution of material within a given design domain to achieve specific performance goals while satisfying certain constraints.
In topology optimization, the design domain is typically divided into smaller elements, and the material properties of each element are varied to optimize the performance of the structure. The goal is to find the optimal distribution of material to achieve the best possible performance while minimizing the use of material.
Parameter estimation sets the objective function automatically.
