COMSOL software Optimization Module User's Guide, introduce the use of optimization module
The Optimization Module provides a general interface for calculating optimal solutions to engineering problems within the COMSOL product family. It allows users to treat model inputs, such as geometric dimensions and material properties, as control variables and model outputs as objective functions. The module is designed to solve two main classes of problems: design problems where the goal is to find values that yield the best performance, and inverse problems, such as parameter estimation, where the goal is to determine parameter values that match measured data.
The module can solve design problems to find control variables that yield the best performance and inverse problems to determine parameters that match measured data.
Examples of design problems include structural optimization, antenna design, and process optimization.
Examples of inverse problems include geophysical imaging, nondestructive testing, and biomedical imaging.
