Goal_
Structural optimization runs for the purpose of achieving a Goal. ANSYS takes CATIA parameters, goes over every single one of them, and negotiate between them to achieve a Goal. Even in the case where multiple results are available, ANSYS stops the optimization as soon as it arranges the first available set of parameters. The software doesn't consider what parameter to calculate first, unless user assigns priority to parameters.

Boundary_
User can set Boundary for each parameter for the purpose of not losing the original form, or of considering the available material size. If the prior parameter reaches the boundary, and yet the Goal is not satisfied, ANSYS starts negotiating secondary parameters. Therefore, there are some cases where ANSYS doesn't give any answer. In those cases, user needs to reconsider the Goal, or give Boundaries more flexibility.

Stochastic Analysis_
Field of mathematics dealing with a process involving a randomly determined sequence of observations each of which is considered as a sample of one element from a probability distribution. also deals with Numerical Analysis. ANSYS employs Stochastic Analysis to go over and negotiate between multiple parameters to achieve a Goal within each prioritized Boundary.
