CST Studio Suite® offers automatic optimization routines for electromagnetic systems and devices. CST Studio Suite models can be parameterized with respect to their geometrical dimensions or material properties. This enables users to study the behavior of a device as its properties change.

Users can find the optimum design parameters to achieve a given effect or fulfill a certain goal. They can also adapt material properties to fit measured data.

CST Studio Suite contains several automatic optimization algorithms, both local and global. Local optimizers provide fast convergence but risk converging to a local minimum rather than the overall best solution. On the other hand, global optimizers search the entire problem space but typically require more calculations.

High-performance computing techniques can be used to speed up simulation and optimization for very complex systems, or problems with large numbers of variables. The performance of global optimizers in particular can be greatly improved with the use of distributed computing.
