CST Studio Suite® offers automatic optimization routines for electromagnetic systems and devices. This allows users to check how the behavior of a device is affected as its properties change, fit material properties to measured data, and find the optimum design parameters to achieve a given effect or fulfill a certain goal.
CST Studio Suite contains several optimization algorithms, both local and global, each suited to different situations. Local optimizers provide fast convergence, but risk converging to a local minimum rather than the overall best solution. Global optimizers on the other hand, typically require more calculations, but they search the entire problem space.
For very complex systems, or problems with large numbers of variables, high-performance computing techniques are available to speed up simulation and optimization. The performance of global optimizers in particular can be greatly improved with the use of distributed computing.
