Allows you to create constraint objects to limit the changes that the optimizer can make. Often an optimization finds a configuration that optimizes the objective you provided, but is unrealistic because it violates overall design constraints such as weight, size, speed, or force limits.
To avoid results that violate the design constraints, you can create constraints for the optimization. The optimization analysis improves the objective as much as possible without violating the constraints.
Each constraint object creates an inequality constraint. The optimization keeps the value of the constraint less than or equal to zero. You can create an equality constraint, in effect, by creating a pair of constraint objects, each the negative of the other.
Note: | You do not need to create an explicit constraint to limit the value of a design variable. You can do this directly by setting properties for the variable. |
Constraints can involve the simulation results, but are not required to do so. You can constrain overall size, weight, or other factors that depend only on model data. In these cases, use the function or macro/variable option for the constraint, and ignore the analysis data that Adams View supplies. Instead, compute the constraint directly from the appropriate model data.
